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

v0.8.3 main and dev braches

Ollama Version (if applicable)

No response

Operating System

Ubuntu 22

Browser (if applicable)

Chrome 145 , Firefox 147

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

The UI should display the file contents when opening the attachment.
The model should be able to access and use the attachment contents in its response.

Actual Behavior

The model responds that it can’t see the file / can’t access the attachment contents.
Clicking the attachment in the UI shows “No content” even though the file size is displayed (e.g. 1.8 KB).

Steps to Reproduce

Open a chat.

Attach a .txt file to the chat message and send it.

Ask the model to summarise or quote the file contents.

In the UI, click the attached file to view it.

Additional Information

Attached files (e.g. .txt) appear to upload (size is shown), but the UI displays “No content” when opened, and the model reports it can’t see/read the attachment contents.

This is happening on 0.8.3 and also on the dev branch (as of writing).

I previously commented in a knowledge collections issue ([#21299
(https://github.com/open-webui/open-webui/issues/21299) ). I’m now thinking that issue may be a symptom of the same underlying problem if knowledge ingestion uses the same attachment/file pipeline.

This seems to happen in both embedding and bypass RAG modes.

cannot reproduce, usually only happens when file processing failed or file is still processing

cc @silentoplayz can you reproduce?

Just tested again on latest dev - also does not appear there either. Just works.

Document extraction or RAG pipeline issue on your end most likely. Check your logs

hey @Classic298 Thank you for your feedback, I have indeed found out the issue and it was the RAG pipeline that was the issue, it was unrelated. Thank you for trying to replicate this, I appreciate your time.
