## Summary Fixes a bug where the queue/execute button was incorrectly disabled with a warning icon when creating a new empty workflow, due to stale missing nodes data persisting from a previous workflow. ## Root Cause When switching from a workflow with missing nodes to an empty workflow, the `getWorkflowPacks()` function in `useWorkflowPacks.ts` would return early without clearing the `workflowPacks.value` ref, causing stale missing node data to persist. ## Changes - **`useWorkflowPacks.ts`**: Explicitly clear `workflowPacks.value = []` when switching to empty workflow - **`useMissingNodes.test.ts`**: Add test case to verify missing nodes state clears when switching to empty workflow ## Test Plan - [x] Added unit test covering the empty workflow scenario - [x] All 20 unit tests pass - [x] TypeScript type checking passes - [x] Manual verification: Create workflow with missing nodes → Create new empty workflow → Button should be enabled ## Before 1. Open workflow with missing nodes → Button disabled ✅ (correct) 2. Create new empty workflow → Button still disabled ❌ (bug) 3. Click valid workflow → Button enabled ✅ ## After 1. Open workflow with missing nodes → Button disabled ✅ 2. Create new empty workflow → Button enabled ✅ (fixed) 3. Click valid workflow → Button enabled ✅ [screen-capture (2).webm](https://github.com/user-attachments/assets/833355d6-6b4b-4e77-94b9-d7964454cfce) 🤖 Generated with [Claude Code](https://claude.com/claude-code) ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-6774-bugfix-Fix-execute-button-incorrectly-disabled-on-empty-workflows-2b16d73d365081e3a050c3f7c0a20cc6) by [Unito](https://www.unito.io)
