Crash in the omni.graph.core.get_node_type. How to debug?

Hi, I’m writing an extension in omniverse, and I have a piece of code that does

name = ‘omni.isaac.conveyor.IsaacConveyor’

omni.graph.core.get_node_type(name)

I have an exception from get_node_type().
How can I troubleshoot this? Debugger does not step into the get_node_type()

Hi @Mykola-777 - Are you following below mentioned docs:

Yes, I went even deeper.
I’m calling on_add_track() in ConveyorBuilderWidget (omni.isaac.conveyor\omni\isaac\conveyor\scripts\ui\conveyor_builder.py:277)

I’ve created my own instance of the ConveyorBuilderWidget and I’m calling
self.widget.on_add_track(None)

This gives me an exception with a logs ending with

File “s:/warehouse/_build/windows-x86_64/release/_exts/omni.graph/omni/graph/core/_impl/controller.py”, line 471, in
obj.create_node(
File “s:/warehouse/_build/windows-x86_64/release/_exts/omni.graph/omni/graph/core/_impl/graph_controller.py”, line 225, in create_node
return obj.__create_node(obj, args=args, kwargs=kwargs)
File “s:/warehouse/_build/windows-x86_64/release/_exts/omni.graph/omni/graph/core/_impl/graph_controller.py”, line 307, in __create_node

<class ‘omni.graph.core._impl.errors.OmniGraphError’> OmniGraphError: Could not create node using unrecognized type ‘omni.isaac.conveyor.IsaacConveyor’. Perhaps the extension ‘omni.isaac.conveyor’ is not loaded?

The exception is raised inside of call to og.get_node_type

    elif isinstance(node_type_id, str):
        node_type = og.get_node_type(node_type_id)

in the S:\warehouse_build\windows-x86_64\release_exts\omni.graph\omni\graph\core_impl\object_lookup.py:531,
method def __node_type(node_type_id: NodeType_t) → og.NodeType:

I would like to debug inside of the omni.graph.core, but it exposes .dll only, a file
s:\warehouse_build\windows-x86_64\release_exts\omni.graph.core\bin\omni.graph.core.plugin.dll

Hope this brings some context.
