`vercel alias` no longer assigning domains

Help

Current versus Expected behavior

We previously were running vercel alias in CI to alias our preview deploys to a specific URL. The CLI is returning the same response as usual:

Vercel CLI 37.5.3
> Assigning alias subdomain1.example.com to deployment subdomain2.example.app
Fetching domain subdomain1.example.com under org-slug
Creating alias
> Success! https://subdomain1.example.com now points to https://subdomain2.example.app [1s]

and yet inside of vercel, the domain is not assigned and it doesn’t not go to the correct build. This used to work but seems to have stopped working.

Help?

I wasn’t able to replicate this issue with my test app using the vercel alias set [deployment-url] [custom-domain] command. :thinking:

Are you able to share an example deployment URL and subdomain so I can investigate what went wrong?

Thanks for your reply @amyegan

I just submitted a support case! Login – Vercel

Thanks for letting me know! If you can share an example deployment URL and custom domain on that ticket, it will help your support engineer investigate more quickly.
