Comfy Cloud - Some outputs couldn't be saved. Try running the workflow again.

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Any workflow using the DWPoseEstimator, such as the Wan2.2 Animate ComfyUI native workflow, succeeds upon completion of the node.

### Actual Behavior

The workflow stops with a popup stating "Some outputs couldn't be saved. Try running the workflow again."

### Steps to Reproduce

Run a workflow using the node in Comfy Cloud

### Debug Logs

```powershell
"Some outputs couldn't be saved. Try running the workflow again."
```
