Alias domain - Error! You don't have access to the domain platform.example.com under team-shared.

When this action runs:

deployment.yml

name: Vercel Deployment
on:
  push:
    branches: [ 'staging' ]

env:
  FONTAWESOME_NPM_AUTH_TOKEN: some-token
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Build w node@16
        uses: actions/setup-node@v3
        with:
          node-version: '14.19.3'
          # cache: 'npm'
          # cache-dependency-path: package-lock.json
      - run: |
          npm ci
          npm run build

      - uses: amondnet/vercel-action@v25
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN}}
          # vercel-args: '--prod'
          vercel-org-id: ${{ secrets.ORG_ID }}
          vercel-project-id: ${{ secrets.PROJECT_ID }}
          scope: team-shared
          working-directory: ./
          alias-domains: |
            platform.example.com

On the domain assigning step

> npx vercel -t *** --scope team-shared alias https://platform-staging-fdlk83hsa-team-shared.vercel.app/ platform.example.com

Build fails and the output looks like this:

Vercel CLI 25.1.0

I have the same issue when using the alias-domains parameter. It looks like it's related to the vercel set alias command of the Vercel CLI, I opened a discussion on the Vercel community here: vercel/community#953.

In the meanwhile, I fixed the issue by using the aliases REST API with a custom script:

workflow.yml

      - [...]
      - name: Set alias
        uses: actions/github-script@v6
        env:
          previewUrl: ${{ steps.deploy.outputs.preview-url }}
          aliasDomain: [my-alias-domain]
          vercelToken: [my-vercel-token]
          vercelTeamId: [my-vercel-team-id]
        with:
          script: |
            const setAlias = require('./.github/scripts/set-alias.js');
            await setAlias({ github, context });

set-alias.js

const axios = require('axios');

module.exports = async ({ github, context }) => {
    const { vercelToken, previewUrl, vercelTeamId, aliasDomain } = process.env;

    const deployment_url = previewUrl.replace('https://', '');

    const configs = {
        headers: { Authorization: `Bearer ${vercelToken}` },
    };

    const { data: deployment } = await axios.get(`https://api.vercel.com/v6/deployments/${deployment_url}`, configs);

    await axios.post(
        `https://api.vercel.com/v2/deployments/${deployment.id}/aliases?teamId=${vercelTeamId}`,
        { alias: aliasDomain },
        configs,
    );
};
