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

v0.8.2

Ollama Version (if applicable)

v0.16.1

Operating System

Ubuntu 24.04

Browser (if applicable)

Chromium (Playwright)

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

Initiated a chat with Web Search capability:

What are the top business news for today?

Retrieved 3 sources

  • Searching the web
  • Searching
    What are the top business news for today?
  • Searched 11 sites
    Business News - CNBC
    Business News - Latest Headlines on CNN Business | CNN Business
    Business: US & International Top Business News | AP News

  • Retrieved 3 sources

Expected chat to generate a response, but none was generated. Container logs immediately dumped the exception and stack trace shown below while still indicating the "Searching" step.

Actual Behavior

Web search runs okay and returns URLs; NLTK downloads data packages okay; the pipeline then stalls/fails. Exception stack trace is output in the container logs.

Steps to Reproduce

Running Open WebUI v0.8.2 and sending a chat message that invoked web search (Open WebUI -> LiteLLM (perplexity_search) -> SearXNG) and web loader (Playwright). Model used is Gemma3 via Ollama.

  1. Enable "Web Search" chat capability.
  2. Enter chat message: "What are the top business news for today?"

OK. I believe this is fixed in 0.8.3 as I don't see the exception anymore.

I tried these versions: v0.7.2, v0.8.3, v0.8.5, v0.8.6, v0.8.7.
Clean install, without data. using DDGS, Backend Random. Tried other search engines as well and didn't find a working one.

Also having a similar issue on v0.8.12

Have tried with DDGS + Random aswell as Searxng, same issue. Web search has been working fine for the past 3 months (Been updating regularly). It broke for me around the time I updated to v0.8.10+
