I am using the latest version of Open WebUI.
Installation Method
Git Clone
Open WebUI Version
v0.6.28
Ollama Version (if applicable)
0.11.10
Operating System
Windows 10
Browser (if applicable)
any
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 chatting the LLM's response should be printed on screen
Actual Behavior
On chatting, the LLM replies "Unexpected token 'd', "data: {"id"... is not valid JSON"
Unexpected token 'd', "data: {"id"... is not valid JSON
Logs & Screenshots
Additional Information
i have been using openwebui for almost a year now,
on the latest update i've been facing this error. I've got no way to know whats wrong, i have tried many older versions still the same error.
it would be great if you point me to the right direction.
its a beautiful project.
