Unable to build docker image on Windows

Perhaps I'm doing something wrong, but I can't build docker image on Windows using Rancher Desktop v1.8.1:

Sorry, wrong repository (can't delete issue).

Wrong repo. You’re trying to build the native Valhalla image from https://github.com/valhalla/valhalla.

no idea what rancher is, but it seems it’s not copying over the .git (hint: hidden) folder. Better ask on another forum, not GitHub, hardly anyone doing anything on windows in our repos.

Build from dockerfile in this repo succeeded.
