make.jl fails with git error

[Ralph Kube]

Hi,
I'm trying to generate documentation for my project following these instructions: https://documenter.juliadocs.org/stable/man/guide/

I created a docs subfolder with make.jl :

using Documenter
push!(LOAD_PATH,"../src/")
using my_package

makedocs(sitename="my_package Documentation")

When I run make.jl I get the following error:

*[main][~/julia_envs/my_package/docs]$ julia --color=yes --project make.jl 
ERROR: LoadError: ArgumentError: Unable to automatically determine remote for main repo.
> `repo` is not set, and the Git repository has invalid origin.
Configure `repo` and/or `remotes` appropriately, or set `remotes = nothing` to disable remote source
links altogether (e.g. if not working in a Git repository).

The git configuration for my_package works fine though and git origin is set correctly.
