Description (last modified by )
This Django 3.1.3, I only see this with Sqlite, it works fine with MySQL and Postgres.
When I do a path lookup with values like Bob.objects.values("my_json_field__position") if there is an integer, float or bool in "position" then I get a JSON decode error.
Strings, nones, dicts and lists all work, fetching the top level dict works and filtering on the path lookup works.
TypeError: the JSON object must be str, bytes or bytearray, not float
