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

v0.6.41

Ollama Version (if applicable)

0.13.1

Operating System

Ubuntu 22.04

Browser (if applicable)

Chrome

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

uploading files to knowledge or chat sessions should produce embeddings via ollama as configure
http://ollama:11434/api/embed

Actual Behavior

aiohttp.client_exceptions.ClientResponseError: 404, message='Not Found', url='http://ollama:11434/api/embed'

2025-12-04 17:06:40.767 | ERROR | open_webui.retrieval.utils:agenerate_ollama_batch_embeddings:773 - Error generating ollama batch embeddings: 404, message='Not Found', url='http://ollama:11434/api/embed'

Steps to Reproduce

open openwebui in browser
go to chat session
upload file
embedding failed with index out of range error

Logs & Screenshots

Additional Information

I can curl embeding successfully from within the openwebui docker container so it's not a routing issue.
This just started happening after a recent update.

Originally created by @stevewillett on GitHub (Dec 4, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/19755 ### Check Existing Issues - [x] I have searched for any existing and/or related issues. - [x] I have searched for any existing and/or related discussions. - [x] 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!). - [x] I am using the latest version of Open WebUI. ### Installation Method Docker ### Open WebUI Version v0.6.41 ### Ollama Version (if applicable) 0.13.1 ### Operating System Ubuntu 22.04 ### Browser (if applicable) Chrome ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have **provided every relevant configuration, setting, and environment variable used in my setup.** - [x] 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). - [x] 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 uploading files to knowledge or chat sessions should produce embeddings via ollama as configure http://ollama:11434/api/embed ### Actual Behavior aiohttp.client_exceptions.ClientResponseError: 404, message='Not Found', url='http://ollama:11434/api/embed' 2025-12-04 17:06:40.767 | ERROR | open_webui.retrieval.utils:agenerate_ollama_batch_embeddings:773 -
