error: stack overflow (possible infinite recursion)

[0x006E]

A new flake lock update, is making this error. I rolled back version for this flake and it works without any issue. I'm not sure what information I can give you that is relevant.

Error:

$ nix flake check
warning: Git tree '/home/nithin/nix' is dirty

error: stack overflow (possible infinite recursion)

The niri config is mostly copied from yours.

[sodiboo]

i've... been writing a very lengthy explanation of this all. for the past HOUR. and i refreshed the page. normally github keeps my draft. but it's gone.

it's late, i'm defeated, and crushed by this total reset of progress for my documentation.

you can see some of my debugging as it happened in the niri matrix room, it has, uh, parts of what i was gonna write here.

now i'm just pissed. the issue is fixed ,you're welcome. i'm not gonna close it because i'll probably write up more later, perhaps tomorrow. fuck this

[0x006E]

Well, thanks for the fix and the great work. It works great. I haven't joined the matrix, but will do now.
