Supermerger — https://github.com/hako-mikan/sd-webui-supermerger

After each XYZ plot run I see an error in the console:

Error save prompt file [11:24, 4.74it/s] Traceback (most recent call last): File "E:\SD\automatic1111\extensions\sd-dynamic-prompts\sd_dynamic_prompts\callbacks.py", line 24, in on_save png_info = image_save_params.pnginfo["parameters"] KeyError: 'parameters'
