template fails with stack overflow

[blalor]

Describe the issue

Current master is 3c92540. Running nix develop with the output of nix flake init --template github:nix-community/poetry2nix fails with error: stack overflow; max-call-depth exceeded.

Replacing

myapp = mkPoetryApplication { projectDir = self; };

with

myapp = mkPoetryApplication { projectDir = ./.; };

fixes the issue.

This doesn't happen with nix 2.19 on earlier, It only happens with Nix 2.20 or later

I believe this might be the same issue as NixOS/nix#9672
