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

General Version v0.8.8

Ollama Version (if applicable)

No response

Operating System

Red Hat Enterprise Linux release 9.7

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

Hybrid search is working correctly together with Oracle 23ai (as vector store)

Actual Behavior

We are facing almost identical issue/bug as described in https://github.com/open-webui/open-webui/issues/18356 . We are using Oracle 23ai as vector store and when we switched on Hybrid Search (Admin Panel -Settings- Document) and when performing chat based on uploaded document, document search is ending up with error, shown in Open WebUI log - see attached file.

OpenWebUI_oracle23ai.py_UnboundLocalError_Hybrid_Search_20260312.txt

Steps to Reproduce

Setup integration with Oracle 23ai DB as vector store
Switch on Hybrid Search (Admin Panel -Settings- Document)
Upload document into chat and perform search/queries based on uploaded document
