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 sending a request to a connected pipeline using the Oauth or session authentication setting, I expect the the request value inside of

 def pipe(
        self, user_message: str, model_id: str, messages: List[dict], body: dict, __request__: Request = None, 
    ): # -> Union[str, Generator, Iterator]:
        print(f"{__request__ = }")

        yield {"event": {"type": "message", "data": {"content": "the answer was always 4"}}}

as shown in the docs

Actual Behavior

When I send a request to the pipeline and look at the logs, request is None.

INFO:root:stream:false:<generator object Pipeline.pipe at 0xffff7d3b8540>

INFO:root:stream:false:{'event': {'type': 'message', 'data': {'content': 'the answer was always 4'}}}

__request__ = None

INFO:     172.217.165.202:41529 - "POST /chat/completions HTTP/1.1" 200 OK

Steps to Reproduce

1. Set up an Open Webui instance. I used docker and ensure ENABLE_FORWARD_USER_INFO_HEADERS=True
2. Create a pipeline and host it through an endpoint

from starlette.requests import Request
from pydantic import BaseModel

class Pipeline:
    class Valves(BaseModel):
        pass

    def __init__(self):
        self.valves = self.Valves()

    def pipe(
        self, user_message: str, model_id: str, messages: list[dict], body: dict, __request__: Request = None, 
    ): 
        print(f"{__request__ = }")
        yield {"event": {"type": "message", "data": {"content": "the answer was always 4"}}}

3. Make the connection to between the Open Webui instance and pipeline and set the Authentication setting to Oauth or Session.

Additional Information

A version of someone doing this has been documented here which was posted Augusted 25th 2025 which means this worked for some version of open webui before v0.6.25
