string_type error in Pydantic #163

Open jowolf opened 3 weeks ago

jowolf commented 3 weeks ago

I'm getting a string_type error in Pydantic - here's my call:

watchlists = Watchlist.get_public_watchlists (session)

Traceback (most recent call last): File "[,,,] watchlists = Watchlist.get_public_watchlists (session) File "/home/joe/traderjoe/env/lib/python3.10/site-packages/tastytrade/watchlists.py", line 83, in get_public_watchlists return [cls(i) for i in data['items']] File "/home/joe/traderjoe/env/lib/python3.10/site-packages/tastytrade/watchlists.py", line 83, in return [cls(i) for i in data['items']] File "/home/joe/traderjoe/env/lib/python3.10/site-packages/pydantic/main.py", line 193, in init self.__pydantic_validator__.validate_python(data, self_instance=self) pydantic_core._pydantic_core.ValidationError: 2 validation errors for Watchlist watchlist-entries.12.instrument-type Input should be a valid string [type=string_type, input_value=None, input_type=NoneType] For further information visit https://errors.pydantic.dev/2.8/v/string_type watchlist-entries.13.instrument-type Input should be a valid string [type=string_type, input_value=None, input_type=NoneType] For further information visit https://errors.pydantic.dev/2.8/v/string_type

Lots of other calls work fine on this session prior to this call, so I know the session is fine and was established OK j

More info / workaround: When I pass counts_only=True, it works (but returns the full results):

watchlists = Watchlist.get_public_watchlists (session, counts_only=True)
print()
print ('Watchlists')
pp ([wl.name for wl  in watchlists], indent=2)

returns:

Looks like some of the TT watchlists have an instrument type of None! I was able to reproduce. Will be fixed in next release.
