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

Other

Open WebUI Version

v0.8.10

Ollama Version (if applicable)

No response

Operating System

Rocky

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

We followed procedure for upgrade.

We did 2 migrations one went without problems, other one failed with error message:

@ibeex commented on GitHub (Mar 11, 2026):

history = chat_data.get("history", {})
messages = history.get("messages", {})

# Skip if messages is not a dict (sometimes it's a list in the database)
if not isinstance(messages, dict):
    continue

for message_id, message in messages.items():

this is fix we added in runtime

Thanks.
We are facing exactly the same problem.
Is there a way to apply only this patch when are working with kubernetes and your official image tag?
