app crashes on jpg image

[shroukkhan]

Hi, The app works fine when I try to get a png image. however, whenever, it is a jpg image, it crashes with:

/var/www/imageproxy/node_modules/image-resizer/node_modules/aws-sdk/lib/request.js:32 throw err; ^ TypeError: Cannot read property 'ext' of null at Image.Object.defineProperty.set (/var/www/imageproxy/node_modules/image-resizer/src/image.js:194:34) at Response.

Any idea what is going on ?

I am not able to replicate this issue sorry. From the looks of the error it would appear that possibly your image is not correct, or can not be found?

[shroukkhan]

Hi,i forgot to update this. Yes, it was indeed an issue with the s3 provider. they did not manage the images well. all worked well after they fixed their end .

@shroukkhan

I have the same issue with some but not all requests.

Any chance you could elaborate on what the problem was for you and how you fixed it?

[leesiongchan]

@shroukkhan I have the same issue too.

[shroukkhan]

Hi @andrewcuthill @ahlee2326

I tracked down my issue to the case where it turned out it actually did NOT download the jpg image at all. In your case , make sure the jpg image is infact downloaded before passing it to resizer

[leesiongchan]

It seems it crashes when I access to root ( / ).

[andrewcuthill]

@shroukkhan I'm not sure what you mean by downloaded, but I tend to get a 503 error when I try and access the image directly without any modifiers.

[shroukkhan]

Please make sure the following:

1. use separate aws sdk https://aws.amazon.com/sdk-for-node-js/ and make sure you can indeed download image from s3 bucket
2. Once download is complete , make sure you can access the image from within the node app

---

if step1 and 2 are successful, carry on with the image resizer. In my case, i found the error in step1 ( as in image was not downloadable through s3 sdk ( some kind of corruption in the bucket ) ) and image rezier was trying to resize a non existing image.

fyi, i am not the writer of this module..i am merely a user :)

[andrewcuthill]

Thanks for replying @shroukkhan. What was the cause of the corruption?

I'm really struggling to get to the bottom of this - I've created a new bucket and migrated the content, created a new user in IAM, I can use aws s3api get-object with that user to get an image, yet image resizer will crash.

Sometimes if I restart the dyno, image resizer will successfully get the image.

[shroukkhan]

in my case, the corruption happened because we had migrated from one s3 compatible provider to another s3 compatible provider and they didnt really do their job very well. So i had to upload same images again into the new s3 bucket and then download+resize them through image resizer . Old existing images wont work.

bottom line of the issue is, it happens if you pass a non jpeg image ( or a corrupted image ) to image resizer and ask it to resize it.

@jimmynicol any ideas how I can try and attempt to debug this?

Here's an example - https://s3.amazonaws.com/ii-content/top_picks-image-compressor.jpg
