Custom node ComfyUI_OmniGen_Nodes stopped working after updating ComfyUI 0.3.39 -> 0.3.40

Custom Node Testing

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

Your question

The only change i have made was updating ComfyUI from 0.3.39 to 0.3.40 (and the frontend)
Right after the update the custom node ComfyUI_OmniGen_Nodes stopped recognizing setOmniGenLoader node
(just before update it was working fine. after update ComfyUI suggest to delete setOmniGenLoader node outlining it with a bold red line)

The error i get is:

[ERROR] An error occurred while retrieving information for the 'setOmniGenLoader' node.
Traceback (most recent call last):

KeyError: 'OmniGen'

i removed the node and reinstalled it, but the issue persists.
is there any chance this can be fixed? i doubt the custom node would be updated in foreseeable future?
please help!

additional information:
before removing the node in question:
invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#7'", 'extra_info': {}}

after removing problem node from the workflow it is impossible to add it back as it is absent in the list of available nodes

no other loaders (load diffusion model, load unet.. etc i tried probably all of these) can not connect to "OMNIGEN MODEL" connector
on the OmniGen Sampler node, as it is probably requiring the unique model type. (i was trying to use any alternative model loader. it did not work)
please help
