I’ve been running Discourse forums since some time prior to 2018. I can’t believe that we still have “422 Unprocessable Entity” errors. I’m not even talking about when using APIs, but when writing posts, creating automations, creating categories — basically all sorts of things in the web-based interface. These are incredibly non-user-friendly. Could we please have meaningful, potentially helpful, error messages about what exactly the problem is?
How about if I promise home-made (non-poisonous, of course) cookies?
