When trying to install a pip package using pypi2nix, I get the following error message:

No matter which package I try to install (I also tried "requests" and "pyensembl"), the error message remains the same. Unfortunately, the error message is not very precise, so I'd appreciate any information.
Hi, You are (most likely) using an unstable version of nix which is currently incompatible with pypi2nix.
Yes this is happening with nix flakes. mostly nix versions >=2.4
