I am unable to successfully generate "Generation cancelled."

This is my first time using StableGen. I tested the generation, but I got this Generation Cancelled alert. I have ComfyUI open, and I corrected the server IP. A Scene tab appears in the location I defined as output, but there is no result.

The plugin cancels right after I click generate. I don't know how to fix this.

I can't tell what is the issue unless you provide additional info.
Could you check ComfyUI console and also Blender's console output when clicking on Generate and paste it here?

You may already know this, but this is how you access Blender's console on Windows:

I tested it again today and it worked! I didn't make any changes to the PC other than uninstalling the Adobe suite, but as far as I know, there is no connection between the two. I followed the same procedure and this time, the image was generated.

If I encounter any new problems, I will update here. Thank you very much.

running into a similar issue.

tracking the issue happened while sequential SDXL generation in ComfyUIGenerate class...

the workflow generate method returns an empty dictionary, which is because _execute_prompt_and_get_images runs into some issue that some nodes on ComfyUI side failed. There is no handler to deal with execution_error case, and the while loop just keeps running until it breaks when the downstream node has no data. In my case, it's the KSampler failed to compute matrix multiplication due to the shape differences of the two given matrices.

this seems to be related the version of ComfyUI (v0.3.49), after upgrading to v0.6.0, the issue fixed for some scenes, but still existing for some cases. I think it's the models that being used in controlnet and causes the issue.
