I have searched the existing issues and discussions.
I am using the latest version of Open WebUI.
Installation Method
Docker
Open WebUI Version
v0.6.15
Ollama Version (if applicable)
/
Operating System
Windows
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
Nothing visible, just pollution of the logs
Actual Behavior
chromadb.telemetry.product.posthog:_direct_capture:61 - Failed to send telemetry event ClientCreateCollectionEvent: capture() takes 1 positional argument but 3 were given - {}
chromadb.telemetry.product.posthog:_direct_capture:61 - Failed to send telemetry event CollectionAddEvent: capture() takes 1 positional argument but 3 were given - {}
Steps to Reproduce
I just started it up, that's it. After a short while it gave me this, but stopped after 10-12 messages.
It might also be when I send a request. I think I send 4, and with 3 retries, it could amount to 12 messages.
Logs & Screenshots

It seems that the fault is in chromadb when passing arguments to a dependent library posthog (Requires-Dist: posthog>=2.4.0), for this to work properly, it need to change that requirement to force posthog>=2.4.0,<6.0.0
Maybe adding posthog>=2.4.0,<6.0.0 to requirements could solve that issue.

Intended behaviour here, chromadb telemetry is disabled by default.
