invalid value "nas1" for --exit-node; must be IP or unique node name

[borecz]

I am trying to use tailscale/github-action@v2 Github action. You can find my Github action code below

name: tailscale test

on:
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Tailscale
        uses: tailscale/github-action@v2
        with:
          authkey: ${{ secrets.TAILSCALE_AUTHKEY }}
          args: --reset --accept-routes --exit-node nas1
          hostname: github-action-${{ github.run_id }}

However, when running above action, I am getting error invalid value "nas1" for --exit-node; must be IP or unique node name

I can successfully run Tailscale using nas1 as exit node when using Tailscale CLI

sudo tailscale up --authkey "${{ secrets.TAILSCALE_AUTHKEY }}" --hostname "github-action-${{ github.run_id }}"
sudo tailscale up --reset --accept-routes --exit-node "nas1" --hostname "github-action-${{ github.run_id }}"

Could you guide me on how to debug this issue, please?
