ReferenceError: ReadableStream is not defined

I am trying to use setup-uv on self-hosted GHE servers. I am getting the following error on both v5 and v6.

Run astral-sh/setup-uv@v6
/home/runner/_work/_actions/astral-sh/setup-uv/v6/dist/setup/index.js:110867
webidl.is.ReadableStream = webidl.util.MakeTypeAssertion(ReadableStream)
                                                         ^

My workflow file was pulled directly from the documentation.

    steps:
      - uses: actions/checkout@v4

      - name: Install uv
        uses: astral-sh/setup-uv@v6

      - name: Set up Python
        run: uv python install

Hi can you please provide more information?

• Do you mean you are running on GHES?
• Do you mean you are using self-hosted GitHub Action runners?
• If yes, is this a supported Operating System?
• Is this the whole log output?

[samuel-odinware]

I am attempting to run this action from a GitHub Enterprise server using self-hosted runners. Runner OS is Ubuntu 22.

As for the log, everything up to that step succeeds. The posted log is everything from the failed Install uv step.

What version is your actions runner and what version is your node runtime?

[samuel-odinware]

I am going to close this issue since I am not able to provide the requested information (managed by another team). While I was unable to get this action working with our runners, I was able to come up with another solution. Thank you for your time and keep up the great work.

As a hint to your internal team: I asked for those version numbers because I suspect that the node version being used by your runners is too old. Should be v20
