No inner node DTO found for id [366:32]

### 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

Normal workflow executing without errors like before.

### Actual Behavior

When a group containing a sub-blueprint in the workflow is muted, executing the workflow results in a red error message in the top-right corner of the page which says 'No inner node DTO found for id [xx:xx]' and the workflow fails to run, with no error information reported in the background. This issue seems to occur only when there is a sub-blueprint; it appears to execute normally without a sub-blueprint, though I'm not entirely sure yet. This seems to have started occurring since version 0.14.1, and now that I've updated to 0.15, the issue persists.
