Describe the bug

I'm trying to upload and download a couple of images. I think I uploaded successfully tomy S3 bucket. Because at least I'm able to download the image through the AWS Console. But I'm not able to get it showing up in my React Native app. I can get the following link. but it always throws a 403 error. I followed the documentation here: https://docs.amplify.aws/react-native/build-a-backend/storage/download/#generate-a-download-url But it doesn't work.

Expected behavior

get my images showing up in my app.

Reproduction steps

Install dependencies. Run expo ios Signup Upload a profile photo You won't be able to see your profile photo when signing in

Code Snippet

// Put your code below this line.

UPLOADING:

const profileKey = 'profile-picture/' + user?.sub + '_' + getImageName(profilePicture!);
      const isUploadProfileError = await fetchImage(profilePicture!)
      .then(data => uploadData({
        key: profileKey,
        data,
        options: {
          accessLevel: 'guest'
        }
      }))
      .then(result => result.state === "ERROR");

      if(isUploadProfileError) {
        setStatus('error');

        return;
      }

      DOWNLOADING

      const result = await getUrl({
      key,
      options: {
        accessLevel: 'guest',
      }
    }).catch(console.log);

    return result?.url ?? null;

Now I'm able to get the image but I needed to update permissions for both the bucket and the file manually. do you know if is there a way to upload a file using uploadData method from aws amplify with the correct permissions? at least I want the images showing up with public permissions. @cwomack

[ashika112]

COuld i understand your case case a little bit more. Like the folder structure u are trying to upload to and how you want the permission to work between the folders.

With Amplify Gen2, you can now do more flexible folder permissioning refer docs https://docs.amplify.aws/gen2/build-a-backend/storage/

[fimbres]

Hey @ashika112, basically I want to store cover images for some records in the database. I think they can have public access. But following the Amplify Docs: https://docs.amplify.aws/react-native/build-a-backend/storage/upload/, I'm able to upload images to s3, but they always upload with no public access, even after assigning accessLevel: 'guest', which is supposed to give public access to the file. So I'm just wondering how can I assign public access with 'aws-amplify/storage'.

I will take a look at the docs you shared tho, thanks for your response.

[ashika112]

Thanks @fimbres . On your network tab can you check if both upload/download calls are made to the same place in s3 bucket?

[fimbres]

Yes I see the calls @ashika112, but they returned the 403 access denied error.

[fimbres]

Hey, any thought on this one? @ashika112 @cwomack

[ashika112]

Can u post screenshot of ur network call it will help us debug faster. Make sure to redact sensitive info. This can only happen when there is a mismatch with the two below.

That said , things i would check is

1. If ur IAM policies associated has the right permission set
2. The request URL for upload and download hits the right folders

[ashika112]

Also another thing in ur code, is to Make sure to either pass in the same profileKey to both uploadData and getUrl. Or store the return key from uploadCall and pass that to getUrl

@fimbres, we've officially launched the Gen 2 Developer Experience for Amplify as of 5/06/24. Check out our launch blog post for more information, but can you let us know if you're still experiencing this blocker in Gen 2 now that it's generally available?

Also, when you say that you're looking for "public" access on the bucket... do you mean a truly public URL/bucket access that anyone can access outside of the unauth/auth roles for your app?

[fimbres]

hey @cwomack @ashika112, thank you for your response. I was debugging a couple days ago. I deleted my old bucket and created a new one using amplify cli. And suddenly my issue was solved. Now I'm able to see all the files from my console and more important from my app. Thanks for the help and your time!

[ashika112]

@fimbres Happy to hear things worked out for you. Let us know if there is anything else. I will close this issue since the issue seems to be resolved.
