Need Help: Stable Diffusion 3.5 large Deployment Error on RunPod

Trying to deploy stabilityai/stable-diffusion-3.5-large on serverless RunPod using ComfyUI but getting this error:
“Missing 'workflow' parameter”

Anyone knows if this model works on RunPod? Which option is best — ComfyUI, vLLM, or SG-Lang?

Appreciate any quick tips or examples!

Im nott sure if vllm or sglang does support this model, so comfyui

Maybe in your input it should have the key 'workflow', that worker uses the comfyui workflow (in api format)

probably you'd have to download the model manually into network storage, like in the readme of the serverless worker in github, or build your own image with the models inside
