unable to access namespace in overlays

[Yash-Garg]

I am facing this error when trying to access namespace in my overlays/default/default.nix file.

Am I doing something wrong w.r.t the overlay docs?

I tried, getting the same issue.

Can you share your config in a GitHub repository?

Can you share your config in a GitHub repository?

Sure, here's the flake.nix file. I haven't pushed the namespace changes on the repo since it wasn't working.

[Yash-Garg]

Hey, sorry to bother you but did you get a chance to look at the issue? @jakehamilton

[jakehamilton]

Haven't gotten around to taking a look just yet, sorry.
