### 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

### Actual Behavior

运行工作流

### Steps to Reproduce

运行工作流

### Debug Logs

```powershell
Failed to enqueue job for processing
```

### Other

_No response_

Start by reproducing the workflow in Comfy Cloud with custom nodes disabled, then capture the full server response and logs around “Failed to enqueue job for processing.” No source files or tests are named; a useful resolution would require a reproducible workflow, complete logs, and confirmation that the job can be accepted.
