Upload error 400 after onProgress reports all the way through 100%

Has anybody experienced a 400 error after the progress goes all the way to 100%?

I'm using a signed URL and this used to work up until a few months ago.

We had this problem today, we were using on the client:

<ReactS3Uploader ... uploadRequestHeaders={{ 'x-amz-acl': 'public-read' }} >

And on the server:
ACL: 'private',

Changing in the client x-amz-acl to private solved the case.

We had the same issue, it started happening yesterday. @mparedesi fix did the trick.
Weird thing is that we had these setting for over 5 years now. Looks like AWS fixed a really old bug this week.

@mparedesi Fixed our issue as well. Just started a few days ago for us too.

Weirdly had this today. On our frontend component we didn't provide the uploadRequestHeaders prop but after checking the docs, it is set to 'public-read' as default. And in the backend we used 'private'. So this was the issue. @mparedesi thanks for pointing it out.
