Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

0.6.33

Ollama Version (if applicable)

No response

Operating System

ubuntu 22.04

Browser (if applicable)

No response

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

The application should interact with Redis on AWS ElastiCache without throwing exceptions or losing messages.

Actual Behavior

Occasionally, the application raises the following exception during normal operation without breaking the service:
redis.exceptions.ResponseError: unknown command 'keys', with args beginning with: {open-webui}:ydoc:documents:*
When this occurs, a message in process may be lost.
(Full error log attached below.)

Steps to Reproduce

I do not have consistent reproduction steps. The issue occurs sporadically under normal usage conditions.

Environment
OS: Ubuntu 22.04
Python: 3.12 (inside virtual environment)

Key Environment Variables:

  • REDIS_KEY_PREFIX="{open-webui}"
  • ENABLE_WEBSOCKET_SUPPORT="true"
  • WEBSOCKET_MANAGER="redis"
    Also tested with:
  • REDIS_CLUSTER=True

Redis-compatible service: Valkey 8.1 (AWS ElastiCache)
