Hi,
When using the S3Connector transformer with System credentials, if those credentials are invalid, performing an upload operation still produces an output with a URL as if there were no issues. It doesn't upload the file, it just posts a warning to the log. This is tricky to catch.
Performing a List or Download opertaion with invalid credentials causes the transformer to output through the <Rejected> port with an error, letting us neatly terminate the workspace.
Is there anyway to get the Upload operation to also reject when the credentials are invalid?



For all other operations (e.g. List or Download), the transformer outputs through the <Rejected> port as expected.
