Error message

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

What it means

Thrown by rebaseFlowDraft when the flow draft exists but the flow has never been deployed. Rebase only makes sense when a deploy moved ahead of the draft's fork base; with no deployed version there is no target, and the draft already sits on the latest state.

Solutions

1. Deploy the flow first, then rebase if it changes again afterwards
2. Skip rebasing and deploy the draft directly — it is already current
3. Check the path/workspace if you expected an existing deployment
