No flow draft found for "${path}".

Error message

No flow draft found for "${path}".

What it means

Thrown by rebaseFlowDraft when no flow draft is stored for the path (or the draft value is a string/undefined rather than a flow object). Rebase diffs the draft against a newer deployed version; without a draft there is nothing to re-apply, so the tool refuses instead of returning a null diff.

Solutions

1. Create a flow draft with the flow edit tools before rebasing
2. Confirm the path matches the item you forked
3. If the draft was already discarded, re-apply the saved your_changes diff with the flow edit tools
