Add a "getErrorMessage" method, or similar

Every API is different about how it throws back errors. It's quite important that we show a useful message to the user, rather than "Bad request" or "Invalid status code".

We need a JS function on the global level which automatically tries to pull out errors from the body on failure.

Needs more elaboration as to why this is needed instead of using afterFailure.
An example (use-case) would be helpful.

Maybe this could/should simply be encompassed in the afterFailure, as you say. Here's an example. If you try to create a Salesforce lead with invalid date, you'll get this:

But the actual error is this:

It just feels like we could do more to easily surface that error info on the top level, if it exists. Maybe we just need more effort on the part of the connector developer rather than a falafel implementation.
