BotoServerError repr should include body

[jimfulton]

I occasionally get exceptions like:

BotoServerError: 400 Bad Request

This isn't very helpful. The exception has a body that's much more informative, which
you can see if you turn logging on, but the exception repr should include it too.

What service are you using?

[jimfulton]

CloudFormation (boto.cloudformation)

Here's some more information.

BotoServerError expects the response body to be xml. If it's not xml, it sets the body to None, which wrecks the repr.

The error responses from CloudFormation are JSON (or at least some of them are).

#1010 has a proposed fix for this, with some ongoing discussions about how to make sure this works across all services that return JSON
