Worked. Thank you very much!

For others that might come across the same issue.

.gitmodules looks like this now

[submodule "themes/my-hugo-future-imperfect"]
    path = themes/my-hugo-future-imperfect
    url = ../my-hugo-future-imperfect.git

I just edited the file.

@martingust what do you mean you added the app to your submodules? I’m facing a similar problem and I’m stuck here.

[EDIT] Nevermind - I just didn’t know how to set the relative path to my submodule repositories. I had to change the url in the .gitmodules file to url = ../submodulerepositoryname

Current workaround: Install latest Git on Windows agent. Set system.prefergitfrompath to true in build definition variables.
