For the test to pass I had to change this from new_record_result.json() so I am wondering if this is the right thing to return or not?

Hmm, this returns the method signature and not the JSON dictionary. I'm seeing some test failures like

    def __getattr__(self, name):
        if name in {'_mock_methods', '_mock_unsafe'}:
            raise AttributeError(name)
        elif self._mock_methods is not None:
            if name not in self._mock_methods or name in _all_magics:
>               raise AttributeError("Mock object has no attribute %r" % name)
E               AttributeError: Mock object has no attribute 'json'

/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/unittest/mock.py:634: AttributeError

Is this similar to what you're seeing?

I was seeing TypeError: 'dict' object is not callable but using the lambda function as you suggested fixed it.
