Steps to reproduce

i am using bunny as my media host, the files are getting uploaded but getting an error in uppy like this.

AwsS3/Multipart: Could not read the ETag header. This likely means CORS is not configured correctly on the S3 Bucket.

so the uppy.on('upload-success') methods does not get called and the path's are then not stored in my db

This started happening when i migrated from v3 to v4

I am using this in remix.run app

let uppy = new Uppy({
debug: true,
autoProceed: false,
restrictions: {
maxFileSize: MEDIA_SIZE.TEN_MB,
allowedFileTypes: ['image/*'],
},
}).use(AwsS3, {
shouldUseMultipart: false,
limit: 1,
getUploadParameters: (file) => {
let fileName = file.data.name;
let uploadName = sanitizeNameForUpload(fileName);
let storageZone = bunny_zone;
let storagePath = /images/${uploadName};
let url = https://ny.storage.bunnycdn.com/${storageZone}${storagePath};
return {
method: 'PUT',
url,
fields: {
name: file.data.name,
storagePath,
},
headers: {
AccessKey: bunny_key,
'Content-Type': 'application/octet-stream',
},
};
},
});

uppy.on('upload-success', (file) => {
saveImageFetcher.submit(
  {
    intent: 'save-image',
    name: file.meta.name,
    path: file.meta.storagePath,
    size: file.size,
  },
  { method: 'post' },
);

});

Expected behavior

should show success on upload

Actual behavior

Error: AwsS3/Multipart: Could not read the ETag header. This likely means CORS is not configured correctly on the S3 Bucket.
