S3 PutObject "A header you provided implies functionality that is not implemented"

[Zvikan]

What is the issue?

When using iamlive with proxy mode, when trying to upload object to s3 bucket getting:

An error occurred (NotImplemented) when calling the PutObject operation: A header you provided implies functionality that is not implemented

Error code is 501 NotImplemented.

How to reproduce?

1. Normal proxy iamlive setup
2. run aws s3 cp command into a bucket with empty file

What have you tried to do?

I tried to compare the list of headers between the proxy outputs to the aws cli with --debug , overall the headers seems to be the same.
Can confirm content-length exists, the only header that was in the proxy but not in the aws cli is Accept-Encoding but it seems to be coming from the goProxy, and I saw we're not deleting it.

I also tried to run other PUT method calls like create bucket with proxy, no issues there, just when trying to upload uploads into the bucket.

Note

When trying to upload a non-empty file with the same method above (aws cli), facing different issue where it can't connect to the proxy:

Failed to connect to proxy URL: "http://127.0.0.1:10080"

Hey @Zvikan,

Thanks for raising!

This relates to elazarl/goproxy#367 and intricacies with Go's handling of a specific HTTP request behaviour present in the CLI.

I'm looking deeper into the issue but it may be some time.
