API errors not reported?

@theganyo or who else this concerns

It looks like the -V or --debug -D flags don't return errors from the API itself. Here's what I'm getting back:

Please report a bug if this causes problems.

Is there an option I'm missing here? At first glance, the error messages don't seem to be printed out the console:

https://github.com/apigee/apigeetool-node/blob/2198cff354e7d220dc839aff24db4b0205e28597/lib/commands/deployproxy.js#L369-L377

Though I haven't done a deep-dive into the code yet. Let me know how I can help. Thanks!

Start in lib/commands/deployproxy.js around lines 369-377 and reproduce the API failure using the -V or --debug -D flags. Trace how the API response is handled during policy upload and verify that the API's error details are reported in the console rather than only the status code and stack trace.
