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

When an Action with UserValves is engaged, it should work without error and update the user["valves"] value correctly.

Actual Behavior

An error occurs when using a UserValves-enabled Action.

Additional Information

I discovered this when trying to get the following Action to work without error: https://openwebui.com/f/pad4651/add_to_memories_action_button

The log suggested that an error was occurring, and I traced it to the aforementioned pattern.

Using the example action, with an added uservalves, also produces the issue:

Note that it appears to be due to this outdated (?) pattern:

            if "__user__" in sig.parameters:
                __user__ = (user.model_dump() if isinstance(user, UserModel) else {},)

                try:
                    if hasattr(function_module, "UserValves"):
                        __user__["valves"] = function_module.UserValves(
                            **Functions.get_user_valves_by_id_and_user_id(
                                action_id, user.id
                            )
                        )

In other areas of the repo, similar calls look like:

            if "__user__" in sig.parameters:
                if hasattr(function_module, "UserValves"):
                    try:
                        params["__user__"]["valves"] = function_module.UserValves(
                            **Functions.get_user_valves_by_id_and_user_id(
                                filter_id, params["__user__"]["id"]
                            )
                        )
                    except Exception as e:
                        log.exception(f"Failed to get user values: {e}")
