Check Existing Issues

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

Installation Method

Docker

Open WebUI Version

v0.6.26

Ollama Version (if applicable)

0.11.8

Operating System

Ubuntu

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 am using the Adaptive Memory v3 function https://openwebui.com/f/alexgrama7/adaptive_memory_v2
I should be able to attach a picture in a conversation that's already started even when using a function

Actual Behavior

If I attach a picture to an existing conversation, Adaptive memory v3 crashes with this trace:

Steps to Reproduce

  1. ensure that Adaptive Memory v3 is turned on for the model you are going to use
  2. start a conversation by saying "hi" with this very same model
  3. wait for LLM answer
  4. attach a picture and send
  5. see the open webui logs for trace. the conversation just halts with an spinner-like indicator that something is happening but it has actually crashed silently.

I understand that the onus for fixing this might be on the author of adaptive_memory_v3 but I also don't think that open webui should let a function crash and let the front end behave like something is going to happen. It just hangs there.

maybe you need a more recent version https://github.com/donbcd/adaptive_memory_owui
