Steps to reproduce

1. Not quite sure since I seem to have done something wrong. Anyway this is more general. I am using Formidable to try to upload an audio file to a gcs bucket. For some reason @Google-Cloud tries to parse this as JSON. That is probably my fault and not the issue here.

The issue is the error message in the console from the local Firebase web server. I get the error

"ApiError: Error during request."

This is not very helpful, of course :-(
Fortunately you can get a trace with "console.log". The error is thrown in

functions\node_modules@google-cloud\storage\node_modules@google-cloud\common\src\util.js:193:32

and this line looks like this:

  parsedHttpRespBody.err = new util.ApiError('Cannot parse JSON response');

I think it would be much easier for a developer if this error was made visible directly (instead of " ApiError: Error during request").
