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
Im using comfyui for image generation along with open-webui. Im using this api /api/v1/images/generations
my request payload:
{
"model": "flux1-dev.safetensors",
"prompt": "cat holding hello world!",
"size": "1980x1080",
"n": "1"
}
its should return image in the size of 1980x1080 . But its returning the image in the size of 1024x1024 which is my default image setting. Image Generation api doesn't obey the size of the image from api.
Actual Behavior
/api/v1/images/generations api is not returning the image in the requested size instead its returning image in default size in the settings.
Steps to Reproduce
Generate image via /api/v1/images/generations . with different size in comfyui.
