Steps to reproduce

1- Create a new workflow in the Dify Workflow Creator. 2- Make several changes to the workflow (e.g., adding nodes, connecting nodes, or adjusting settings). 3- Attempt to save or continue editing the workflow. 4- The workflow unexpectedly jumps back to its initial setup state.

✔️ Expected Behavior

• The workflow resets to its initial setup state, losing all recent changes.
• The browser console shows the following error:

{
 "code": "draft_workflow_not_sync",
 "message": "Workflow graph might have been modified, please refresh and resubmit.",
 "status": 400
}

❌ Actual Behavior

• The workflow should save changes or allow continued editing without reverting to the initial setup state.
