AWS S3 - How to fix 'The request signature we calculated does not match the signature' error?

Question

I have searched on the web for over two days now, and probably have looked through most of the online documented scenarios and workarounds, but nothing worked for me so far.

Answer 1

I just experienced this uploading an image to S3 using the AWS SDK with React Native. It turned out to be caused by the ContentEncoding parameter.

Removing that parameter "fixed" the issue.
