Describe the bug

I ran nix flake update on my system config, and lix crash with the following message:

Exception: nlohmann::json_abi_v3_11_3::detail::parse_error: [json.exception.parse_error.101] parse error at line 1, column 1: syntax error while parsing value - invalid literal; last read: '<U+001F>'

fish: Job 1, 'nix flake update' terminated by signal SIGABRT (Abort)

Steps To Reproduce

I don't know if you need my flake.nix or something else I should provide here?

Expected behavior

My inputs should be updated. without crash 😄

guessing it's somewhere in some fetcher, if the api returns bogus json the error isn't properly caught. anyway. tagging this flakes + error handling.
