Your bundle only supports platforms ["x64-mingw32"] but your local platforms are ["ruby", "x86_64-linux-musl"], and there's no compatible match between those two lists.
Link to workflow file and action log?
I guess you are using windows in your build. Can you switch to ubuntu-latest

@printf You can fix this by adding the
ruby platform to your
Gemfile.lock, like this:
bundle lock --add-platform ruby
Then commit this change, and push, and your GitHub Action should work now.
