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

Pip Install

Open WebUI Version

v0.8.12

Ollama Version (if applicable)

v0.18.3

Operating System

Windows 11 Home

Browser (if applicable)

Firefox v149.0 (64-bit)

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

When Fetch URL Content Length Limit is set on the Web Search section of the Admin Settings, I expect to successfully save the value.

Actual Behavior

It returns an error and does not save. It also generates an error in the console.


### Steps to Reproduce

## Steps to reproduce

1. Boot Windows 11 Home 25H2
1. Open Powershell 5.1.26100.7920
1. Navigate to an empty directory
1. Install python. I did this years ago and installed it with `py` included. I do not remember the exact commands. That said, I call `py` to install the specified version that command is followed bellow.
1. Run `py -3.11 -m venv .venv` (As per README.md python 3.11 requirement))
1. Run `./venv/Scripts/Activate.ps1` (Activate environment)
1. Run `python.exe -m pip install --upgrade pip` (To upgrade pip -> not required but a habbit of mine.)
1. Run `open-webui server`
1. Open web browser of choice. I used Firefox v149.0 (64-bit)
1. Open local site on browser: [http://localhost:8080/](http://localhost:8080/)
1. Generate account. Entered email address, username, and password. (Actual values are not relevant to this bug so long as you can remember them to login.)
1. Navigate to `Web Search`.  [http://localhost:8080/admin/settings/web](http://localhost:8080/admin/settings/web)
	- You can use the link here otherwise here are the click through instructions I followed: 
		- I clicked on my name (bottom left corner)
		- Then went to `Settings` with the gear icon. 
		- Then at the bottom left of the Settings modal I selected `Admin Settings`
		- Then on the left side of the Admin Settings I selected `Web Search` with the globe icon.
1. On the Web Searc page
	- Enable Websearch
	- Select Web Search Engine. I chose `google_pse` but I think this choice does not impact the test.
	- Enter your Google PSE API Key (not sure if this is nessicary but I did)
	- Enter the coresponding Google PSE Engine ID (I entered mine)
	- It doesn't matter what value you set for `Fetch URL Context Length Limit` when you save in the powershell console you get the generated error.

Originally created by @taggedzi on GitHub (Mar 27, 2026). Original GitHub issue: https://github.com/open-webui/open-webui/issues/23127 ### 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 Pip Install ### Open WebUI Version v0.8.12 ### Ollama Version (if applicable) v0.18.3 ### Operating System Windows 11 Home ### Browser (if applicable) Firefox v149.0 (64-bit) ### 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 When `Fetch URL Content Length Limit` is set on the Web Search section of the Admin Settings, I expect to successfully save the value. ### Actual Behavior It returns an error and does not save. It also generates an error in the console. ``` ### Steps to Reproduce ## Steps to reproduce 1. Boot Windows 11 Home 25H2 1. Open Powershell 5.1.26100.7920 1. Navigate to an empty directory 1. Install python. I did this years ago and installed it with `py` included. I do not remember the exact commands. That said, I call `py` to install the specified version that command is followed bellow. 1. Run `py -3.11 -m venv .venv` (As per README.md python 3.11 requirement)) 1. Run `./venv/Scripts/Activate.ps1` (Activate environment) 1. Run `python.exe -m pip install --upgrade pip` (To upgrade pip -> not required but a habbit of mine.) 1. Run `open-webui server` 1. Open web browser of choice. I used Firefox v149.0 (64-bit) 1. Open local site on browser: [http://localhost:8080/](http://localhost:8080/) 1. Generate account. Entered email address, username, and password. (Actual values are not relevant to this bug so long as you can remember them to login.) 1. Navigate to `Web Search`. [http://localhost:8080/admin/settings/web](http://localhost:8080/admin/settings/web) - You can use the link here otherwise here are the click through instructions I followed: - I clicked on my name (bottom left corner) - Then went to `Settings` with the gear icon. - Then at the bottom left of the Settings modal I selected `Admin Settings` - Then on the left side of the Admin Settings I selected `Web Search` with the globe icon. 1. On the Web Searc page - Enable Websearch - Select Web Search Engine. I chose `google_pse` but I think this choice does not impact the test. - Enter your Google PSE API Key (not sure if this is nessicary but I did) - Enter the coresponding Google PSE Engine ID (I entered mine) - It doesn't matter what value you set for `Fetch URL Context Length Limit` when you save in the powershell console you get the generated error. <img width="1326" height="870"
