Scripted Workflow Execution Fails with KeyError: '0' in "comfyui-easy-use"

[linfen0]

When i use this node's Loader ComfyUI Easy use error occured regardless to virtual,or real mode.However, the same workflow runs successfully when executed through the ComfyUI frontend.

Actual Behavior:
The workflow fails with the following error:

[Impact Pack] ComfyUI-Impact-Pack: Error on prompt - several features will not work.
'workflow'
[EasyUse] Loading models...
[EasyUse] Load LORA: sdxl_lightning_8step_lora.safetensors: 1.0, 1.0, LBW=None, A=None, B=None

ComfyUI-Easy-Use has some weird behavior that breaks ComfyScript and potentially other frontends. It assumes if unique_id (the id of the current executing node) containing ., the part after . is the node id, while it's not for ComfyScript. It should raise the same error even if you use the workflow/image generated by ComfyScript in ComfyUI's frondend.

https://github.com/yolain/ComfyUI-Easy-Use/blob/0daf114fe8870aeacfea484aa59e7f9973b91cd5/py/libs/utils.py#L188-L195:

def is_linked_styles_selector(prompt, unique_id, prompt_type='positive'):
    unique_id = unique_id.split('.')[len(unique_id.split('.')) - 1] if "." in unique_id else unique_id
    inputs_values = prompt[unique_id]['inputs'][prompt_type] if prompt_type in prompt[unique_id][
        'inputs'] else None
    if type(inputs_values) == list and inputs_values != 'undefined' and inputs_values[0]:
        return True if prompt[inputs_values[0]] and prompt[inputs_values[0]]['class_type'] == 'easy stylesSelector' else False
    else:
        return False

I've created an issue to ComfyUI-Easy-Use: yolain/ComfyUI-Easy-Use#682

At the moment, you can workaround this issue by changing this line to id = f'{type}_{type_id}':

ComfyScript/src/comfy_script/runtime/data/__init__.py

Line 23 in 21fcbaf

id = f'{type}.{type_id}'

I'm not sure if I should commit this change, as it looks like only ComfyUI-Easy-Use has this behavior.
