HTTP 500 error with DreamCompute

[ktdreyer]

When I set up a connection to DreamCompute, I get an HTTP 500 error during client.images().listMembers("")

I'm using Endpoint URL https://iad2.dream.io:5000/v2.0, with an Openstack Auth v2 credential.

ServerResponseException{message=Internal Server Error, status=500, status-code=INTERNAL_SERVER_ERROR}

It looks like Throwable.getMessage() doesn't tell us quite enough about the error from the API. How can I get more information about what went wrong?

I am afraid this is tricky. I presume you can not wiretap the conversation so the 2 options I see are

• research the openstack4j ability to log communication details I have personally never got working or
• run the client in debugger and pause at HttpEntityHandler.java:51

Any tips for running in a debugger? Do you use Eclipse?
