I recently started seeing some issue with rebuilding my NixOS config. I traced it down to an issue with homemanager, but I’m unsure how to proceed. Whenever I try and list my nix profiles, I get a JSON parsing error.
Logging output from home-manager:

When I follow the suggestion in the logs and run nix profile list I get:
[stusmall@desktop:~]$ nix profile list
error: [json.exception.parse_error.101] parse error at line 1, column 1: attempting to parse an empty input; check that your input string or stream contains the expected JSON
Any suggestions on what I should try next to troubleshoot? Almost any nix profile interactions just gives me a JSON error. I tried verbose and debug logging, but couldn’t get anything more than this parsing error.
