Sorry at this time I don't have the details of the error that errored in the error handler. I'll see if I can capture more details.

Hi @rrehbein, I will close this PR for now. However, if this is still something you think is needed in the AWS SDK for PHP, please feel free of opening a new PR base on the current branch, and make sure you provide an issue associated with it, with a reproducible code so we can understand why the suggested change is needed.

Thanks!
