Script "${path}" is not deployed; there is no newer version

Error message

Script "${path}" is not deployed; there is no newer version to rebase onto.

What it means

Thrown by rebaseScriptDraft when the script has a draft but no deployed version — rebase exists to port draft changes onto a deploy that moved ahead of the draft's fork base, and with no deploy there is no newer target. The draft is already based on the only state that exists, so rebasing is meaningless rather than merely impossible.

Solutions

1. Deploy the script first; rebase only matters once a newer deploy exists
2. Skip rebasing — the draft is already current, so just deploy the draft
3. If you expected a deploy to exist, check you are targeting the right path and workspace
