Creating ComfyuiBase for MaskBlur in Comfyui_Essentials

[timriopelle]

Hey Francisco,

Firstly, thanks for these amazing nodes. Having a lot of fun with them.

I am trying to create a Mask Blur (Using the ComfyuiBase) which accesses the Comfyui_Essentials custom node folder. Here is the class of the script in the folder:

class MaskBlur: @classmethod def INPUT_TYPES(s): return { "required": { "mask": ("MASK",), "amount": ("INT", { "default": 6, "min": 0, "max": 256, "step": 1, }), "device": (["auto", "cpu", "gpu"],), } }

And then here is my script in the ComfyuiBase:

{ 'class_type': 'MaskBlur', 'inputs': [ {'name': 'mask', 'outputs': ['mask'], 'opt': False} ], 'outputs': ['mask'] }

comfyui.nodes.update_input_nodes(nuke.thisNode())

I have 2 user knobs for the amount (amount) and device (device), however when I add this node to my workflow and execute, I get the:

JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

You noted this is something with an empty result and not something you can fix. But I was just curious if the Essentials folder may not be getting recognized, or if I am missing something. My workflow works without this node, then when I add it, it's broken. No worries if you can't do anything, I was just curious if you had any advice. Thanks!

Just an update: I tried creating a node (InvertMask) from the ComfyuiBase that I knew was in the same script / location as other nodes you created, and I am still getting this same JSONDecodeError.

{ 'class_type': 'InvertMask', 'inputs': [ {'name': 'mask', 'outputs': ['mask'], 'opt': False} ], 'outputs': ['mask'] } comfyui.nodes.update_input_nodes(nuke.thisNode())

Closing this. I've found a work around. Breaking was related to chaining nodes together. When isolating the ComfyUIBase to function independently, I seem to be having things work correctly.
