The --scope flag was specified, but there's no value for it available.
In order to make it work, you need to specify a value for the --scope flag. This needs to be the slug or ID of the team as which you'd like to act or the username or ID of a user you'd like to act as.
As an example, if your team URL is https://vercel.com/my-team, you would set --scope to my-team.
