Bug Report

Description

Hello,

I helped into packaging Open-WebUI in Nix these last days (https://github.com/NixOS/nixpkgs/pull/316248, https://github.com/NixOS/nixpkgs/pull/317705) and since then, I'm using it on a server in my basement, so far, I'm super happy, I really love it.

I started to import my "Knowledge Base" why is essentially a directory with PDFs on different topics.

In my document library, I have uploaded this paper: https://hal.science/hal-04482192 which is freely accessible.

After a couple of minutes, the embeddings are done, and I open a new chat, select that document using # <tab>, and submit my request.

But I never get a reply... see the log below.

^

At this point, the open-webui systemd service is dead and I must restart it to get it working again.

However, when I try to make a query on the same document I upload inline in the chat window, it works pretty fine:

I don't use specific settings or a fancy model:

Environment

Open WebUI Version: 0.2.5
Ollama (if applicable): 0.1.41
Operating System: Linux NixOS
Browser (if applicable): Firefox

Reproduction Details

Confirmation:

I have read and followed all the instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.

Installation Method

A couple of lines in the NixOS configuration file:

    services = {
      open-webui = {
        enable = true;
        environment = {
          OLLAMA_API_BASE_URL = "http://127.0.0.1:11434";
          HF_HOME = "/var/lib/open-webui/";
          SENTENCE_TRANSFORMERS_HOME = "/var/lib/open-webui/";
          WEBUI_AUTH = "False";
        };
        openFirewall = true;
        host = "0.0.0.0";
      };

      ollama = {
        enable = true;
      };
    };
