Underlying dependency yarl not accepting NoneType parameter values?

[mijolabs]

AsyncClient.search_recent_tweets() (and probably Tweepy's other methods using yarl) does not accept NoneType values for certain parameters, despite Tweepy documentation listing them as an acceptable.

I have a class method calling search_recent_tweets with since_id and next_token parameter values set to None by default.

async def search_recent(
    self,
    search_query: str,
    since_id: str = None,
    next_token: str = None,
    ) -> dict:

The method later calls search_recent_tweets() with the provided parameters, like

return await self.search_recent_tweets(search_query, since_id=since_id, next_token=next_token, ...)

Which results in yarl throwing a TypeError (unless a valid value has been provided to since_id and next_token).

r = await twitter.search_recent("tweepy")


Traceback (most recent call last):
...
File ".../lib/python3.9/site-packages/yarl/_url.py", line 916, in _query_var
    raise TypeError(
TypeError: Invalid variable type: value should be str, int or float, got None of type <class 'NoneType'>
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x104992880>

Could this have something to do with yarl not supporting boolean values, and that includes NoneTypes too?

My current workaround is to create a dict inside the method with the func params and only add since_id/next_token if they're not None, then pass the **params to search_recent_tweets() that way. It's not pretty, but works.

Thanks for the bug report! This should be fixed now.
