## Describe the problem/error/question
When calling a sub-workflow containing a …Wait (Webhook) node, the return data is incorrect:
- When called as Agent Tool: Returns data from node before Wait
- When called as Workflow: Returns initial input data
- Expected: Should return data from last node after webhook completion
## Steps to Reproduce
1. Create sub-workflow with:
- Initial API call
- Wait (Webhook) node
- Final data processing
2. Call this sub-workflow from main workflow
3. Wait for webhook completion
4. Check returned data in main workflow
## Current Behavior
- When called as Agent Tool: Returns data from the node before the Wait node
- When called as Workflow: Returns only the initial input data
- Webhook executes successfully but final data is not returned
## Expected Behavior
Should return the processed data from the last node after webhook completion
## Technical Details
- Using Wait node in 'Webhook' mode
- Webhook successfully triggers and completes
- Sub-workflow executes completely
- Issue occurs in data return to parent workflow
## What is the error message (if any)?
## Please share your workflow/screenshots/recording
