'str' object has no attribute 'error'

[MrTin]

Describe the bug
December 6-7 we would see this exception thrown a few hundred calls per day. They stopped for a while but reappeared again on Jan 2. It also looks like APIs were completely down for about 15 minutes yesterday, as we could see another exception with Bad Gateway: The upstream server is unavailable, please try again... during that shorter timeframe.

To Reproduce
This seems to be random with intermittent issues on the Nylas API itself.

Expected behavior
Better exception handling and bubble up a more descriptive error that we can use to handle this case.
