Twitter list by nadrieril failed with error 400

[Nadrieril]

I use Twitter lists to easily manage which users' tweets I want to get as RSS feeds. Since two weeks ago, some (but not all) of my lists are failing with the error Trying to get property 'id_str' of non-object.

The failing query string is: ?action=display&bridge=Twitter&context=By+list&user=nadrieril&list=cool_math&filter=&format=Json.
This is on my self-hosted instance, running on commit 25cff9c.

This list fails, but this one works, and I have no idea why. It also seems that any new list I add fails.

Interestingly, this is correlated with the existence of https://twitter.com/nadrieril/lists/wholesome and inexistence of https://twitter.com/nadrieril/lists/cool_math . I have no idea what causes one to work and the other to fail, except that the one that fails was created later.

Seems to be working, if you change cool_math to cool-math
https://feed.eugenemolotov.ru/?action=display&bridge=Twitter&context=By+list&user=nadrieril&list=cool-math&filter=&format=Json

[Nadrieril]

Oh wow, that does work! Is there a known rule for Twitter changing symbols like that?
As a fallback I would like it if it was possible to give a list ID directly to rss-bridge instead of going via username & list name

I don't know. Just remembered that slug is expression, where chars that are not alphabetical or numbers are converted to "-".

Agree with suggestion. I will add "feature-request" tag to this issue. Maybe someone will implement it.

Fixed by #1834, thanks!
