Primitive nodes are not working #11483
Description
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 primitive node is working correctly, and the connection point is yellow.
Actual Behavior
Modifying the primitive node did not affect the connected nodes; the connection points are shown in grey.
Steps to Reproduce
Use the official SDXL Simple Example template.

I previously installed the portable version of ComfyUI and encountered this problem when using primitive nodes. So I installed the desktop version, which worked fine at first, but then it started showing this issue after a short time. The join point on the right side of the primitive node, which was originally yellow, has now turned gray.
The only custom node I installed is ComfyUI-Lora-Manager. I've tried disabling all custom nodes, but the problem persists.
