Hi @sonatard 👋,
The action uses SemVer notation for go-version input. Therefore, you need to specify the version as 1.24.0-rc.1 instead of 1.24rc1. Please update your workflow file to use the correct format:

steps:
  - uses: actions/checkout@v4
  - uses: actions/setup-go@v5
    with:
      go-version: '1.24.0-rc.1'
  - run: go version

For more details on the supported version syntax, you can refer to the setup-go documentation.
