Check Existing Issues

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

Installation Method

Docker

Open WebUI Version

v0.6.15 (latest)

Ollama Version (if applicable)

0.9.3

Operating System

Arch

Browser (if applicable)

Firefox

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

I'm able to connect to stable difussion and connect it with OpenWeb UI

I'm using the stable difussion docker image from:
https://github.com/simonmcnair/stable-diffusion-webui-docker

Setting up the accounts on OpenWebUI Produces the error below.

Actual Behavior

Steps to Reproduce

Enable image generation

One thing to note:

http://localhost:7860/sdapi/v1/sd-models returns "not found"

This was an issue because the stable-diffussion container didn't have API enabled.

Use: environment: - CLI_ARGS=--allow-code --medvram --xformers --enable-insecure-extension-access --api

For auto.

I'm going to write a new issue for this, since it didn't validate that there was an actual SD api underneath I think that's the "open-webui bug" here.
