I have searched the existing issues and discussions.
I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

V0.6.5

Ollama Version (if applicable)

No response

Operating System

Ubuntu server 22.04

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

I was trying to embed a HTML content into chat using this template: {{HTML_FILE_ID_[file_id]}}

Actual Behavior

This is my file when access by file_id:

I can download it using "/content" path but when I use the template {{HTML_FILE_ID_[file_id]}}, I get this url: "http://localhost:1234/api/v1/files/bb791128-cf54-4c66-8af5-878dbca4bebe/content/html" with the error bellow:

I'm using open-webui v0.6.25.

I haven't found any similar issues nor solutions.
Please help me !!!

Steps to Reproduce

Install open web-ui using docker
Install this function https://openwebui.com/f/omar97/visualize

https://openwebui.com/f/omar97/visualize seems to be a year old, most like the function itself needs to be updated.
