Issue with "Expecting property name enclosed in double quotes" Error

[chillzzone]

Hi - I hope this post finds you well!

I'm writing to seek assistance with a challenging error that I've encountered while working on my AnimateDiffusion ComfyUI project. Any help or guidance would be greatly appreciated.

Error occurred when executing BatchPromptSchedule: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

File "C:\Users\home\ComfyUI\ComfyUI\execution.py", line 153, in recursive_execute
output_data, output_ui = get_output_data(obj, input_data_all)
File "C:\Users\home\ComfyUI\ComfyUI\execution.py", line 83, in get_output_data
return_values = map_node_over_list(obj, input_data_all, obj.FUNCTION, allow_interrupt=True)
File "C:\Users\home\ComfyUI\ComfyUI\execution.py", line 76, in map_node_over_list
results.append(getattr(obj, func)(**slice_dict(input_data_all, i)))
File "C:\Users\home\ComfyUI\ComfyUI\custom_nodes\ComfyUI_FizzNodes\ScheduledNodes.py", line 122, in animate
animation_prompts = json.loads(inputText.strip())
File "json\__init__.py", line 346, in loads
File "json\decoder.py", line 337, in decode
File "json\decoder.py", line 353, in raw_decode

Thanks so much!!

Also I have a prompt with a structure like this:

"0": "prompt"

Which has worked in the past...

I'm beginning to wonder if there could be any limitations on the length of the prompt itself?

Currently, my prompt contains approximately 20,000 frames of data. Could such a long prompt length potentially contribute to the error I've been encountering?

I have a feeling there might have been a missed comma or quote somewhere in the prompt. Try using ctrl + f with either to be absolutely sure. You can always post the prompt here or in DMs if you would like to keep the prompt private and I can help debug

Batch Prompt Schedule:

text: "0": "(smile:pw_a)", "24": "(sad:pw_a)", "48": "(angry:pw_a)"

max frame:48

I doubt you're still trying to figure this out but for anyone in the future, my issue was the types of quotation marks being used. On the Mac keyboard the quotation marks are slanted “0” but in BatchPromptSchedule it looks like it only likes straight quotation marks like this "0"
