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

Error message

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

What it means

Thrown by rebaseAppDraft when the app draft exists but the app has no deployed version with files to diff against. Rebase ports draft changes onto a newer deploy; with no deploy there is no target, so the operation is rejected rather than producing a meaningless diff.

Solutions

1. Deploy the app first; rebase only once a newer deploy exists
2. Deploy the draft directly — with no prior deploy the draft is already current
3. Confirm you targeted the correct app path and workspace
