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

v0.8.1 (latest)

Ollama Version (if applicable)

No response

Operating System

Winddows 11

Browser (if applicable)

Firefox

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

On an upload of a ***.ts file it is processed as every other text based file.

Actual Behavior

Typescript files ***.ts are rejected with this warning: "File type video/vnd.dlna.mpeg-tts is not supported for processing". Typescript files are mis-detected as video/vnd.dlna.mpeg-tts files.

Steps to Reproduce

  1. Go to Open WebUI and upload a simple TypeScript file, e.g. test.ts containing:

console.log("hello");

  1. It gets rejected.
  2. Rename to 'test.js'.
  3. works fine.
