FIX: adapt error message extractor to the new format (#1507)

Recently, I've seen some chatCompletion errors rendered as "[object
Object]". Doing some debugging, I see the returned error object does not
contain `error` or `details` attributes, but `message` (See image
attached).

I've changed the codebase to support this attribute.
