Description (last modified by Gordon Wrigley)

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

..\..\.venv\data_browser\lib\site-packages\django\db\models\query.py:287: in __iter__
    self._fetch_all()
..\..\.venv\data_browser\lib\site-packages\django\db\models\query.py:1308: in _fetch_all
    self._result_cache = list(self._iterable_class(self))
..\..\.venv\data_browser\lib\site-packages\django\db\models\query.py:111: in __iter__
    for row in compiler.results_iter(chunked_fetch=self.chunked_fetch, chunk_size=self.chunk_size):

    value = converter(value, expression, connection)

    return json.loads(value, cls=self.decoder)
