errors in the SD3 Ultra Node should not stop the workflow

[EricRollei]

I often run a workflow with several branches using the same prompt to generate images based on the same prompt but different platforms - ie Dalle3, SDXL, SD3 Ultra, Pixart Sigma. SD3 Ultra has the most sensitive content violation parameters and quite often Dalle3 etc would continue to generate images however, SD3 Ultra node raises the error to a pop-up window instead of printing to the console, which halts the workflow. The SD3 Ultra node prints to the console a random generated image in base 64 (when ComfyUI is started with --verbose).

It would be so much better for the node to print the error to the console rather than raise a popup error window, and return an image (black, random, blurred) than halt the workflow. An enhanced version of the node would be one which also had a boolean output which could tell the workflow if an error had occurred.

Here's the error raised that halts the workflow below. SAI seems to be much more sensitive than Dalle3. I'm photobashing old classic paintings, and having OpenAI vision write prompts based on those. I'd say SAI triggers a content violation on 1/10 images where as Dalle3 hits it 1/50 but it never halts the workflow since it outputs a black image.

Error occurred when executing Stability Image Ultra:
