I think you're misunderstanding the "Load Prompt from Layer" functionality. It's not for loading the workflow from a Comfy image.
This button will only work when you have a group layer selected, product of a previous generation. It's intended to reproduce all the data of that specific generation in your plugin so you can do it again without having to manually configure it.
The plugin automatically crafts the required workflow for each mode when you press the "Start" button. If you want to inject more complex workflows (a totally optional feature), you can do that in your "workflow" tab, although by the way how ComfyUI handles the nodes with ids can be a bit tricky. I suggest reading the wiki of this repo to clear your doubts.

I have not used Krita before today and I installed it only to try to use this plugin, so this could be something I did wrong in the installation process for the plugin. I've been able to get img2img working, but when I load a PNG and then select "Load Prompt from Layer" I get the error below. I tested this with several images. I tested each image by dropping it onto ComfyUI and they all load the workflow just fine. I assume that the prompt is being pulled out of the workflow, so I tried several different workflows, including the default simple workflow, but they all fail. From the final error, "Expecting value: line 1 column 1 (char 0)" my assumption is that it's not getting the JSON from the image at all. Here is the full error, with a screenshot below, if that helps.
