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

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:

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: https://github.com/vercel/community/discussions/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,
    );
};
