Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.7.2

Ollama Version (if applicable)

N/A

Operating System

Ubuntu

Browser (if applicable)

N/A

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

An image is output in the chat. When image generation is selected. I have verified the prompt is sent to ComfyUI.

Actual Behavior

When using image generation it fails. Postgres is the database. This is the error in the output: [ERROR: (psycopg2.errors.UndefinedTable) relation "chat_file" does not exist
LINE 2: FROM chat_file
^

[SQL: SELECT chat_file.id AS chat_file_id, chat_file.user_id AS chat_file_user_id, chat_file.chat_id AS chat_file_chat_id, chat_file.message_id AS chat_file_message_id, chat_file.file_id AS chat_file_file_id, chat_file.created_at AS chat_file_created_at, chat_file.updated_at AS chat_file_updated_at
FROM chat_file
WHERE chat_file.chat_id = %(chat_id_1)s AND chat_file.message_id = %(message_id_1)s ORDER BY chat_file.created_at ASC]
[parameters: {'chat_id_1': '96d004ff-1645-4ebd-b9a1-6c16a2bd152b', 'message_id_1': 'd8182b91-592a-489f-85b1-fa8f2057c760'}]`

Steps to Reproduce

Attempt to generate an image.

I am unable to reproduce this issue on the latest dev branch. I also use Postgres (PGVector) for my Open WebUI instances database.
