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

0.6.6

Ollama Version (if applicable)

No response

Operating System

Ubuntu 22.04.5 LTS x86_64 (Virtualized)

Browser (if applicable)

Zen Browser 1.12b (Firefox 138.0.1)

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 listed steps to reproduce the bug in detail.

Expected Behavior

When enabling search, the model is supposed to generate a search query and use that for the search

Actual Behavior

Instead of generating a search query, it errors out with Error: object of type 'NoneType' has no len() and searches that using whatever engine is provided (in my case duckduckgo)

Steps to Reproduce

  1. Enable Web Search in the settings
  2. Ask any model to search for anything

### Additional Information

I use models from OpenRouter, whenever I try to use the search feature with whatever search engine I pick, it never manages to generate a search query and just constantly searches for `Error: object of type 'NoneType' has no len()`

Can you use the model openrouter.google/gemini-2.0-flash-exp:free normally in chat?
Otherwise try disabling search query generation in the admin settings.

Yes I can use all models from openrouter correctly in normal chat and they even work with image generation, but as soon as I try to do web search it breaks

I don't really see any error messages in the logs. What RAG settings do you have set? what is your GLOBAL_LOG_LEVEL set to? It's odd that it would fail silently without logs.

Most of my settings are just the defaults that come with OpenWebUI's Docker Image so dunno what to say
