Ruby and Rails Github Action exit code 16

I am trying to set up a continuous integration workflow with Github actions for a new Rails project. This is the error:

2022-05-21T17:07:01.1242737Z Your bundle only supports platforms ["x86_64-darwin-19", "x86_64-darwin-21"] but
2022-05-21T17:07:01.1243516Z your local platform is x86_64-linux. Add the current platform to the lockfile
2022-05-21T17:07:01.1244782Z with `bundle lock --add-platform x86_64-linux` and try again.

And the configuration file:

name: My workflow
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - uses: ruby/setup-ruby@v1
      with:
        bundler-cache: true
    - run: bundle exec rake

Does anybody know what is the issue?

Thank you very much!
