[andreygevechanov]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

The workflow should run without missing nodes.

Actual Behavior

The workflow shows a missing node error: LTXVReferenceAudio.

Steps to Reproduce

1. Open ComfyUI Desktop
2. Load the LTX-2.3 ID LoRA workflow from templates
3. The workflow shows a missing node: LTXVReferenceAudio

Debug Logs

No crash or terminal errors.

The issue occurs directly when loading the workflow:
Missing node: LTXVReferenceAudio

Other

Description

The official LTX-2.3 ID LoRA workflow in ComfyUI Desktop shows a missing node: LTXVReferenceAudio.

Environment

• ComfyUI Desktop: 0.8.28
• ComfyUI Core: 0.18.5
• GPU: RTX 4090

Steps to reproduce

1. Open LTX-2.3 ID LoRA workflow from templates
2. Observe missing node error

Expected behavior

Workflow should run without missing nodes

Actual behavior

Missing node: LTXVReferenceAudio

Notes

This seems to be a packaging/sync issue since this is an official workflow included in ComfyUI Desktop.

I think the issue lies in templates referencing nodes that do not exist in the backport release branches of core ComfyUI, which should be fixed when we go back to normal master releases. This is on core side AFAIK.

Thanks for the detailed report. This does look like a packaging/sync issue with the bundled workflow.
