IndexError: list index out of range when initializing after updating comfyui

here: https://github.com/andrewharp/ComfyUI-EasyNodes/blob/a2aeb8bfca654b2c4881975f9fc89d03218a2b8b/easy_nodes/easy_nodes.py#L718

the module_name getting passed into it is comfyui-router, which does not contain any dots, therefore gets a import failed error:

Traceback (most recent call last):

node folder init code:

# comfyui-router/__init__.py
import easy_nodes
easy_nodes.initialize_easy_nodes(default_category="ComfyUI Router", auto_register=True)

from .comfy_nodes import *  # noqa: F403, E402

NODE_CLASS_MAPPINGS, NODE_DISPLAY_NAME_MAPPINGS = easy_nodes.get_node_mappings()

print("NODE_CLASS_MAPPINGS", NODE_CLASS_MAPPINGS)
print("NODE_DISPLAY_NAME_MAPPINGS", NODE_DISPLAY_NAME_MAPPINGS)


__all__ = ["NODE_CLASS_MAPPINGS", "NODE_DISPLAY_NAME_MAPPINGS"]

# Optional: export the node list to a file so that e.g. ComfyUI-Manager can pick it up.
easy_nodes.save_node_list(os.path.join(os.path.dirname(__file__), "node_list.json"))

the code works fine before I updated comfyui from 0.19 to latest (9c5fca75f46f7b9f18c07385925f151a7629a94f). I tried using auto_register=False, which gets imported successfully, but if i add a debug print the frame is still a string with no dots
