Can't xyz plot a list of checkpoint names

[alessandroperilli]

I have this setup:

The intention is to generate an XYZ plot that modifies the checkpoint name in the SDParameterGenerator node, part of the SD Prompt Reader suite. But I also tried doing the same with an Efficient Loader node.

I receive this error:

Traceback (most recent call last):
File "D:\Tools\ComfyUI\execution.py", line 151, in recursive_execute
output_data, output_ui = get_output_data(obj, input_data_all)
File "D:\Tools\ComfyUI\execution.py", line 81, in get_output_data
return_values = map_node_over_list(obj, input_data_all, obj.FUNCTION, allow_interrupt=True)
File "D:\Tools\ComfyUI\execution.py", line 74, in map_node_over_list
results.append(getattr(obj, func)(**slice_dict(input_data_all, i)))
File "D:\Tools\ComfyUI\custom_nodes\comfyui-browser\nodes\select_inputs.py", line 39, in run
node_id, node_title, widget_name = input.split("::")
ValueError: not enough values to unpack (expected 3, got 1)

I thought that perhaps I'm defining the list of checkpoints in the wrong way.

I use Vivaldi browser (a flavor of Chrome) on macOS to connect to a local ComfyUI server on Windows.
The checkpoints are in the Windows fileserver.

Any help would be greatly appreciated. Thank you.

I have tested it on the basic workflow. But I found no issue on it.

Thanks for checking. As I said, I am encountering the error also with the Efficient Loader:

Is there any chance you can test this particular scenario?

And, regardless, what does the error mean? What is the node missing?
