panic: error generating pkgs

[tim-goto]

Hey, thanks for the great tool :) Unfortunately I have an issue creating the toml file for this repo. To reproduce:

git clone https://github.com/veertuinc/anklet.git
pushd anklet
nix shell github:nix-community/gomod2nix
gomod2nix generate

results in this output:

INFO[0000] Parsing go.mod                                modPath=go.mod
INFO[0000] Downloading dependencies
panic: error generating pkgs: exit status 1

goroutine 1 [running]:

do you have any idea what might be wrong here? Thanks!

EDIT: I have checked the other issues I could find for this error but the patch version is defined in the go.mod and everything else wasn't applicable
