PutObject throws error from AWS SDK

[drgomesp]

When trying to PutObject, I'm getting the following message from AWS SDK:

A header you provided implies functionality that is not implemented

Possibly related to aws/aws-sdk-go#122

Any ideas?

• If you are using minio server and awk-sdk-go, please provide minio version, setup type you use and awk-sdk-go version.

• If you are using minio-go with amazon s3, please use TraceOn() and provide the output.

@drgomesp for minio-go tracing, refer http://docs.minio.io/docs/golang-client-api-reference#TraceOn

This is what I'm getting:

@drgomesp, looks like the bug is fixed in the last master, can you test with it ?

[harshavardhana]

Expect: 100-continue

HTTP/1.1 501 Not Implemented

This is because of the Expect header new S3 endpoints don't yet support this.

[harshavardhana]

@drgomesp can you apply this PR locally and test out for us? #640

Thanks.

[drgomesp]

Apparently the issue happened because the file was empty. It was a problem on my application level, but the error message was not very helpful.

Can we try adding a more helpful feedback?

[harshavardhana]

We cannot server sent the error. We can't know what to say at this point in time. Because the error sent by server is arbitrary. So as a client we can't make sense of anything that went wrong.

[vadmeste]

@drgomesp, were you able to test with minio-go master ?

[deekoder]

@drgomesp I will go ahead and close this issue. Please do reopen if you think we have not addressed this correctly.

[drgomesp]

@deekoder no problem. As I said before, I think we need a proper message when throwing this error. Otherwise, it works fine.
