debug-exceptions = on in instance part in buildout causes requests that return BadRequest to be returned as html instead of json

[wesleybl]

The configuration in question is this:

plone.restapi/base.cfg

Line 41 in 30102e8

debug-exceptions = on

It took me a considerable amount of time to figure out what was going on. I was using the plone.restapi buildout to test validation errors with Volto. Validation errors return BadRequest. So the validation messages were strange in my tests.

I removed this setting and the tests worked. This configuration was added by @tisto in the commit: 8832625

It seems like it is a necessary configuration in performance tests. We have a buildout for performance testing. So I ask if we can leave this configuration there only.
