demo1.json fails on font loading (?)

[tholonia]

Running the /workflows/Graphics/CR_graphics_nodes_demo1.json fails with:

ERROR:root:Failed to validate prompt for output 40: 
ERROR:root:* CR Batch Images From List 44:  
ERROR:root:  - Required input is missing: image_list
ERROR:root:Output will be ignored
ERROR:root:Failed to validate prompt for output 42:
ERROR:root:Output will be ignored
Prompt executed in 0.00 seconds

40 = CR Thumbnail Preview 44 = CR Batch Images From List 42 = CR Image Output

The only change I made was to point to CR_Font_File_list::folder_path = "/usr/share/fonts" for a Linux system

I also tried

/usr/share/fonts/noto and /usr/share/fonts/noto/NotoSerifToto-Regular.ttf (with from_folder)

Where can I learn about the input put values for these nodes? For example:

• CR_Outout_Flow_frames::outout_folder is fixed as "undefined" and can't be changed. What is it looking for?
• In CR_Load_Flow_Frames, what's the difference between input_folder and input_path?

Is there some locations where I can download the files you use in the workflow examples? For example, "depth_leres-0070.png", which is used in the example workflow CR_Animation_A3_SimplePromptScheduling_IterativeDemo_v01b.json.
