fix(auth): return auth_response from exchange_code_for_session instead of response dict

[timu-jesse-ezell]

What kind of change does this PR introduce?

Bug fix

What is the current behavior?

Method started returning dict instead of pydantic object

What is the new behavior?

Return the pydantic object

Additional context

There seems have been a behavior change introduced recently, not sure this was intentional, this method used to return the pydantic model, but here it is returning the json. This is breaking our code after updating. Looks like other methods are still returning the pydantic model, so I think this was a mistake.

Previous implementation for reference, xform=parse_auth_response causes response to be a pydantic model, new code seemed to rely on manually parsing the model, but then returns the wrong one of the two objects.

 async def exchange_code_for_session(self, params: CodeExchangeParams): code_verifier = params.get("code_verifier") or await self._storage.get_item( f"{self._storage_key}-code-verifier" ) response = await self._request( "POST", "token", query={"grant_type": "pkce"}, body={ "auth_code": params.get("auth_code"), "code_verifier": code_verifier, }, redirect_to=params.get("redirect_to"), xform=parse_auth_response, ) await self._storage.remove_item(f"{self._storage_key}-code-verifier") if response.session: await self._save_session(response.session) self._notify_all_subscribers("SIGNED_IN", response.session) return response

Yes, this was a mistake where the variable was only renamed in some places and not others. It wasn't caught because the function does not declare a return type, and mypy infers Any for functions with no declared return type, instead of the usual None (python/mypy#9413).

[o-santi]

I've included both the missing return type annotations, with also some additional ruff reformatting from the last PR.

Fixed in v2.23.0.
