A symlink or does not exist in your `_includes` directory

I am getting this error on GitHub action page

A file was included in themes/docsy/assets/vendor/bootstrap/site/docs/4.5/components/alerts.md that is a symlink or does not exist in your _includes directory.

I tried to use the below CLI:

git clone --recurse-submodules --depth 1 https://github.com/docker/get-involved

and added a new file and able to run the below command:

hugo server
hugo
