Correct way to use git version in a GitHub action .NET Core

Question

I have an API in .NET Core

I'm new in Github actions and I am trying to set a github action that everytime we send a PR, it updates the API project version. I'm working with dependabot, so the idea is that everytime a package is updated, the .NET Core API version is updated too.

I tried to follow this documentation https://gitversion.net/docs/ along but I'm unable to make this work. Does someone have any idea? Much appreciated.

This is what I have so far but I get an error.

This is the error, I know it might be because gitversion not being set correctly, but that's what I saw in the documentation.

the uses' attribute must be a path, a Docker image, or owner/repo@ref`
