Hello, today I’ve been dealing with a problem in AWS File Uploader. All attempts to upload a file fail when I use the ‘Add prefix to filename’ feature. When this is enabled the PUT request to upload the file to S3 returns a 403 with the following response:
SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method.
If I disable ‘Add prefix to filename’ there are no problems.
Can you please advise?
