It is picking up the ujson module from here: https://github.com/davidhalter/typeshed/blob/ae9d4f4b21bb5e1239816c301da7b1ea904b44c3/third_party/2and3/ujson.pyi

Hopefully there is a way we can tell jedi to not use that.

I think we would basically need to fork jedi to fix this (as per discussion in davidhalter/jedi#1809).

Maybe we can get some inspiration from Thonny. It looks like they are monkey-patching instead of forking.
