Check Existing Issues

I have searched the existing issues and discussions.
I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

0.6.16

Ollama Version (if applicable)

0.10

Operating System

MacOS Sequoia 15.4

Browser (if applicable)

Brave

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Using the ComfyUI generation, it should return an image

Actual Behavior

Returns and [ERROR: '143:3'] when clicking on image generation

Steps to Reproduce

pipx install open-webui --python python3.12
brew install comfyui
Open comfyui and go to Workflow > Templates > Image > Flux Kontext Dev Grouped
Save the workflow with Workflow > Export (API)
Open open-webui > Admin Settings > Settings > Images and enable Image generation, Image Generate Engine "ComfyUI"
ComfyUI Base URL: HTTP://localhost:8000
Paste in the workflow generated
In ComfyUI Workflow Nodes enter

Set Default Model: FLUX1/flux1-kontext-dev.safetensors
Seet Image Size: 1920x1280
Set Steps: 20

Additional Information

ComfyUI recently added grouped nodes which has a new syntax so I suspect that that OpenWebUI is expecting a number, but it is now "node:subnode", I can grovel through the code to fix if you would like
