Creating badge via API query works, but returns 422

Dev

I want a way to make groups of badges:

  • bronze -> submitted with certain tag
  • silver -> submitted tag, liked by me
  • gold -> submitted tag, liked by me and 3 other people

I need to make a bunch of them and it’s tedious doing it from the web interface. One day I’ll write a plugin, but until then, I thought I’d do a quick Python script.

I had given up, as it fails with

urllib.error.HTTPError: HTTP Error 422: Unprocessable Entity

but when I glanced again at the badges admin page, I found that my badge had indeed been created. I guess maybe I don’t care, as it does work, but any ideas on why I get this error?

I added a bunch of headers thinking that might somehow help. It didn’t seem to (but they don’t seem to have hurt, either).

You get this error if you try to create a badge that has a name that already exists.
