Karthik Nadig (@karthiknadig) - do you have context here?
Kidsunbo commentedon Sep 12, 2025
#25450 maybe this is related to this issue
eleanorjboyd commentedon Sep 12, 2025
#25450 was just merged yesterday so it wouldn't have been shipped out in time- or are you saying thats the fix?
Kidsunbo commentedon Sep 13, 2025
well, according to the context of the bug in Jedi language serve, the bug might be related to the semantic tokens in Jedi language server. #25450 disables semantic tokens like the previous version did, so that might be the fix. Not verified.

Let us know if you are able to verify if that works- thanks

It works with the latest version.
