Could not find MIME for buffer (null)

[Allaphy]

I have this problem "Could not find MIME for buffer (null)" and i don't know how to fix it. I believe that the problem is in jimp.read. that is the part of the code where i read the images:

var imgs = [pa1, pa2]; // pa1 and pa2 are images URLs. var jimps = []; for (var i = 0; i < imgs.length; i++) { jimps.push(await jimp.read(imgs[i])); }

'imgs[]' are the URLs of the images to read.

• Jimp Version: 0.5.3
• Operating System: Windows 8.1
• Node version: 8.11.4

I’m probably going to need a link to one of your images. I’m pretty sure image urls are working so I’ll need a test image On Wed, Oct 10, 2018 at 8:44 PM Allaphy notifications@github.com wrote:

I experience it too but with files saved locally. I've been using old version (0.2.28) for a long time, then on 2nd October I made an update to 0.5.3. It never happened to me before. It's not reproducible when someone sends you a file because in my situation, for example only 2 of 5 tries crash. When it crashes and then I try the same file, after some time it works. It doesn't make sense.

Right now I tried the file I'm attaching, on 2nd try it worked. 636629e3-dcee-4a34-9c07-99f7aadfbd99.zip

This was successfully printed after file upload:

node_1   | debug: UploadedFileMetadata {
node_1   |   fd: '/app/.tmp/uploads/636629e3-dcee-4a34-9c07-99f7aadfbd99.jpg',

Then this error:

[Allaphy]

the urls aren't aways the same, are urls from discord's avatars (message.author.displayAvatarURL), for example: https://cdn.discordapp.com/avatars/472158887966015508/a64800726ff83aedd350092730484a1e.jpg?size=2048

with me, just some times crashes too, some times works fine, and some times it wont.

[hipstersmoothie]

The following runs without any errors. I'll do a run with a 1000 but I'm not sure this will reproduce it.

Are you able to reproduce this outside the discord server?

const Jimp = require('jimp');

test();

async function test() {
  for (let i = 0; i < 100; i++) {
    const image = await Jimp.read(
      'https://cdn.discordapp.com/avatars/472158887966015508/a64800726ff83aedd350092730484a1e.jpg?size=2048'
    );

    const buffer = await image.getBufferAsync(Jimp.AUTO);
    console.log(i, buffer);
  }
}

[hipstersmoothie]

I feel like maybe the request is failing? you said it had to do with upload. maybe sometimes you do it too soon and the resource isnt quite there yet?

[DavidOndrus]

I'm able to reproduce it with local files, without network so it's not an issue with online files, it's a general Jimp.read issue.

[hipstersmoothie]

You you give me a script like the one i provided above? Currently 700 requests and no errors

[DavidOndrus]

Download my file and use your script with Jimp.read('/app/.tmp/uploads/636629e3-dcee-4a34-9c07-99f7aadfbd99.jpg')

[hipstersmoothie]

Still no luck. How often does it happen for you?

[hipstersmoothie]

Can you put together a repo that demonstrates the issue? I so far have not been able to reproduce. I am also not on windows

[DavidOndrus]

I would not try to reproduce it with tests because even if one of many tries fails, you are not able to repeat the same process with the same result. I mean, if one line printed "null" in the test output above, it's not very useful information I think. I've searched this repo and found a line with the error string we've posted so I would go for investigating the stack trace. If similar errors occur, it's often a problem with thread (asynchronous operations) because it's reproducible e.g. only once per 10 tries.

[hipstersmoothie]

The thing is I can't get it to go wrong even once so i can't even begin to debug the error. the stack trace tells me whats going wrong but I can't write code to handle a case I can't reproduce at least a little.

You said you were able to reproduce the issue locally. Is this not the case?

I'm able to reproduce it with local files, without network so it's not an issue with online files, it's a general Jimp.read issue.

Your statement here would lead me to believe you can at lest reproduce it 1 in 10 times.

I'm not sure how to go forward. Could you just try/catch?

@Allaphy can you point me towards some code that produces the issue?

[Allaphy]

send the buffer to cosole.log i know how to do it, but when i do this, it wont send the message on discord.

should i do something with this buffer ?

[Allaphy]

var p1 = hguData[sort1].user; // String var pa1 = hguData[sort1].avatar; // avatar URL (image) var p2 = hguData[sort2].user; // String var pa2 = hguData[sort2].avatar; // avatar URL (image) var data; var imgs = [pa1, pa2]; var jimps = [];

for (var i = 0; i < imgs.length; i++) { jimps.push(await jimp.read(imgs[i])); }

Promise.all(jimps).then(function() { return Promise.all(jimps); }).then(function(d) { data = d; return jimp.loadFont(jimp.FONT_SANS_16_WHITE); }).then(async function(font) { msg.react("⏳"); data[0].resize(75, 75); data[1].resize(75, 75);

let nova = new jimp(255, 125, '#000000', (err, image) => {});
nova.composite(data[0], 5, 25);
nova.composite(data[1], 130, 25);
nova.print(font, 32, 2, "P1");
nova.print(font, 155, 2, "P2");
nova.print(font, 5, 103, p1);
nova.print(font, 130, 103, p2);
nova.write(`./images/hg/hgtest.png`);
await msg.channel.send({files: [`./images/hg/hgtest.png`]});

[hipstersmoothie]

@Allaphy That code wasn't really doing what you wanted to accomplish. The following does what you intended. I also changed:

• the print calls to center the text within the picture width so you can put any string there now.
• i noticed you weren't properly centering the avatars so i did that too

@DavidOndrus if you provide me an example like this I can try to fix it as well.

const Jimp = require('jimp');

const hguData = [
  {
    user: 'Dan',
    avatar: 'https://avatars0.githubusercontent.com/u/1192452?s=88&v=4'
  },
  {
    user: 'Mary',
    avatar: 'https://avatars3.githubusercontent.com/u/179534?s=460&v=4'
  }
];

const sort1 = 0;
const sort2 = 1;

test();

async function test() {
  const PICTURE_WIDTH = 75;

  const { user: user1, avatar: avatar1 } = hguData[sort1];
  const { user: user2, avatar: avatar2 } = hguData[sort2];

  const images = [avatar1, avatar2];
  const jimps = await Promise.all(images.map(img => Jimp.read(img)));

  jimps.map(img => img.resize(PICTURE_WIDTH, PICTURE_WIDTH));

  console.log('⏳');

  const nova = await Jimp.create(250, 125, '#000000');
  const AVATAR1_START = 25;
  const AVATAR2_START = 150;

  nova.composite(jimps[0], AVATAR1_START, 25);
  nova.composite(jimps[1], AVATAR2_START, 25);

  const font = await Jimp.loadFont(Jimp.FONT_SANS_16_WHITE);

  nova.print(font, AVATAR1_START, 2, { text: 'P1', alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER }, PICTURE_WIDTH);
  nova.print(font, AVATAR2_START, 2, { text: 'P2', alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER }, PICTURE_WIDTH);
  nova.print(font, AVATAR1_START, 103, { text: user1, alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER }, PICTURE_WIDTH);
  nova.print(font, AVATAR2_START, 103, { text: user2, alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER }, PICTURE_WIDTH);

  await nova.writeAsync(`./hgtest.png`);

  console.log('all done!');
  // await msg.channel.send({ files: [`./images/hg/hgtest.png`] });
}

[DavidOndrus]

My code is really simple in this case - it crashes on the first Jimp line (Jimp.read) - in the case where it happened, I also had sails.log.debug before Jimp.read printing uploadedFiles[0] object a "fd" field was properly there:

file.upload(function (err, uploadedFiles) {
      if (err) {
        sails.log.debug(err);
        return res.negotiate(err);
      }

      if (uploadedFiles.length === 0) {
        sails.log.debug('No file was uploaded');
        return res.serverError({error: 'No file was uploaded'})
      }

      const fd = uploadedFiles[0].fd;
      Jimp.read(fd)
        .then(image => {
          const mimeType = image.getMIME();
          return image
            .resize(Jimp.AUTO, 500, Jimp.RESIZE_NEAREST_NEIGHBOR)
            .getBufferAsync(mimeType)
            .then(buffer => {
              //do stuff with buffer
            })
        })
    });

[hipstersmoothie]

Have you been able to reproduce the error outside of sails? As in a just a simple script no server. I still have not been able to reproduce your issue. Currently running this following with your file with no errors so far:

const Jimp = require('jimp');

test();

async function test() {
  while (true) {
    try {
      const image = await Jimp.read('./exampleImages/636629e3-dcee-4a34-9c07-99f7aadfbd99.jpg');
      await image.resize(Jimp.AUTO, 500, Jimp.RESIZE_NEAREST_NEIGHBOR).writeAsync('test.png');
      console.log('wrote image');
    } catch (error) {
      console.log('CAUGHT ERROR!');
      console.log(error);
    }
  }
}

[DavidOndrus]

I didn't try outside of sails because Sails is a must for me in the project, it must work everywhere. You said "I still have now been able to reproduce your issue" - so were you ? Or is it a mistake ?

[hipstersmoothie]

Oops just a typo. Still cannot reproduce. If you cannot reproduce outside of sails then this must be a problem with the interaction between the two.

I have never used sails so i really need you to put together a repo with as little code as possible that showcases the problem. Otherwise I will not be able to fix this at all.

[hipstersmoothie]

To me it seems like this has to be async issues with your code. You've said:

• it happens locally without hitting a network (so it doesn't have to do with jimp's request function)
• it happens when running a sails server with local files.
• it happens sometimes

This leads me to believe that you are not properly awaiting a promise at some point resulting in the image sometimes being there. jimp is just using fs.readFile to read the file on your local machine. If readFile returns a null buffer that generally means that the file is not yet on your system.

Again without a repo showcasing the issue I cannot debug this issue only theorize.

[hipstersmoothie]

@DavidOndrus do you happen to be using webpack?

[DavidOndrus]

No, I don't use webpack. I agree that's a strange issue, I will probably need to resolve this by myself.

[Allaphy]

thank you man, the code is really better now. It still doing the MIME's error (not so mutch like before), but for my case, i could unless send a message to repeat the process so its fine now.

If, eventually this problem get a solution, i'll find out, but for now its not a big problem any more.

[hipstersmoothie]

I'm gonna close this. If someone can put together an example that errors consistently and share it with me feel free to open an issue!

[darrensw777]

Same problem here guys, this fails every time (is it because there is no file extension? If so is there a workaround?):

const image_url = 'https://images.asos-media.com/products/river-island-maxi-dress-with-tie-neck-in-snake-print/10985965-1-snakeprint';

Jimp.read(image_url)
                    .then(image => image.write(`/path/to/images/${lastInsertId}.jpg`))
                    .catch(err => {
                        console.error(err);
                    });

This is the error I get:

[hipstersmoothie]

Write requires a mime type in pretty sure. Nowhere near a computer so u can’t link

[hipstersmoothie]

Jimp.auto as the second param

[darrensw777]

No dice, exactly same error, tried with Jimp.auto and Jimp.AUTO

[hipstersmoothie]

@darrensw777 The following code works for me.

const Jimp = require("jimp");

test();

async function test() {
  const image = await Jimp.read(
    "https://images.asos-media.com/products/river-island-maxi-dress-with-tie-neck-in-snake-print/10985965-1-snakeprint"
  );

  await image.writeAsync("test.jpg", Jimp.AUTO);
}

but your code also just worked when i ran it....

const Jimp = require("jimp");

const image_url =
  "https://images.asos-media.com/products/river-island-maxi-dress-with-tie-neck-in-snake-print/10985965-1-snakeprint";

Jimp.read(image_url)
  .then(image => image.write(`test.jpg`))
  .catch(err => {
    console.error(err);
  });

[hipstersmoothie]

write doesn't return a promise so you should actually use writeAsync

const Jimp = require("jimp");

const image_url =
  "https://images.asos-media.com/products/river-island-maxi-dress-with-tie-neck-in-snake-print/10985965-1-snakeprint";

Jimp.read(image_url)
  .then(image => image.writeAsync(`test.jpg`))
  .catch(err => {
    console.error(err);
  });

what version are you using?

[darrensw777]

Definitely not working still for me with that image url.

Tried:

const Jimp = require('jimp');

const image_url =
    'https://images.asos-media.com/products/river-island-maxi-dress-with-tie-neck-in-snake-print/10985965-1-snakeprint';

Jimp.read(image_url)
    .then(image => image.writeAsync(`test.jpg`))
    .catch(err => {
        console.error(err);
    });

Get the following error:

I only installed this yesterday so presumably the latest version. Installed using NPM

Using with NodeJS v. 11.4.0

OS: Linux 3.10.0-862.14.4.el7.x86_64 x86_64

How can I use and have it not throw a script blocking error? I have a fallback if this fails but it will not fail silently.

[hipstersmoothie]

Since i cannot reproduce this locally an example repo is gonna be needed. Also this has nothing to do with the issue we are using to talk about it so another issue would be cool as well.

aren't you catching and printing the error? the program should continue right?

as I said without a reproducible example I will be little help other than just speculation

[RMCoder198]

I solved this issue by using promise method as suggested in docs instead of using callback method. Another reason i am getting this error is because of having too many images on destination directory. @hipstersmoothie you might try to reproduce it by having 50+ images inside destination directory.

[mayankbytes]

I am also facing same issue, when I gave image path, like following let image = await Jimp.read("./assets/not-button/1.jpg");

But when import my image and then pass it to JIMP.read(), it works, not sure what the issue is

import notButton1 from './assets/not-button/1.jpg'; let image = await Jimp.read("notButton1");

What is difference in both approach and why it is not working in first one? Any leads are appreciated.

@hipstersmoothie

[FridayJew]

The same error, the files are received from the Internet and saved on the disk, but are not read by the jimp module. There are no visible problems with them.

[codan84]

I get this error without fail every time I read certain images from a URL.

My app does a bing image search and then tries to read a random image. some of them read fine, some of them throw an error as described in this issue.

The ones that throw an error, throw it always.

One of the offending images: https://s-media-cache-ak0.pinimg.com/736x/c9/8f/e1/c98fe17dc7de72bb29c34a0c79ef5762.jpg

Here is a repo that reproduces the issue (I am running this on node v10.16.2).

I can provide many more image URLs that always fail.

Example output:
