Failed to register ComfyUI nodes

[hossan-tk9004]

When connecting to ComfyUI, the following RuntimeError appears in the terminal:

[SDN-WRN]: Unused ConditioningAverage  is unregistered
Traceback (most recent call last):

RuntimeError: Error: Registering node socket class: 'STRING,FILE_3D_GLB,FILE_3D_GLTF,FILE_3D_FBX,FILE_3D_OBJ,FILE_3D_STL,FILE_3D_USDZ,FILE_3D' is too long, maximum length is 64

[SDN-INF]: RegNode Time: 1.41s

When this error occurs, the node list in the ComfyUI Node Editor becomes empty, and no nodes can be added.

As a temporary workaround, I added a try~except block around the reg_cls class method near line 2090 in .\ComfyUI-BlenderAI-node\SDNode\nodes.py to ignore the error:

@classmethod
def reg_cls(cls, clss: NodeBase):
    if not cls.is_new(clss):
        return
    try:
        is_in = clss.bl_label in cls.CLSS_MAP
        cls.unreg_cls(clss)
        bpy.utils.register_class(clss)
        cls.CLSS_MAP[clss.bl_label] = clss
        if is_in:
            logger.warning(f"{clss.bl_label} is updated")
        return clss
    except:
        return

With this workaround, the node list is displayed again.

For now this allows me to continue working, but I am not sure whether ignoring the exception could cause other issues.

I would appreciate a proper fix or an update to avoid this registration error.

[Updated Information]

This issue did not occur when testing with Blender version 4.2.
It appears this issue was likely caused by a Blender version mismatch.

Initially, I encountered this issue while testing with Blender 5.0.

[Updated Information]

After restarting Blender 4.2 and checking the ComfyUI Node Editor again from Blender, I encountered the same problem I initially reported.
The ComfyUI node list was empty, and I was unable to add any nodes.

I have temporarily resolved the issue by using the same method described in my initial report (inserting a Try~Except statement).
