In a nutshell

I found attribute error when accessing graphiql page. I use custom context class.

This is the original issue #96.

Describe the Bug

When accessing graphiql endpoint I always see errors in logs. Like this:

TypeError: get_redis_connection() missing 1 required positional argument: 'request'
  File "fastapi/applications.py", line 261, in __call__
    await super().__call__(scope, receive, send)
  File "starlette/applications.py", line 112, in __call__
    await self.middleware_stack(scope, receive, send)
  File "starlette/middleware/errors.py", line 146, in __call__
    await self.app(scope, receive, send)
  File "starlette/middleware/base.py", line 22, in __call__
    await self.app(scope, receive, send)
  File "starlette/exceptions.py", line 58, in __call__
    await self.app(scope, receive, send)
  File "fastapi/middleware/asyncexitstack.py", line 21, in __call__
    raise e
  File "fastapi/middleware/asyncexitstack.py", line 18, in __call__
    await self.app(scope, receive, send)
  File "starlette/routing.py", line 656, in __call__
    await route.handle(scope, receive, send)
  File "starlette/routing.py", line 315, in handle
    await self.app(scope, receive, send)
  File "starlette/routing.py", line 77, in app
    await func(session)
  File "fastapi/routing.py", line 264, in app
    solved_result = await solve_dependencies(
  File "fastapi/dependencies/utils.py", line 498, in solve_dependencies
    solved_result = await solve_dependencies(
  File "fastapi/dependencies/utils.py", line 498, in solve_dependencies
    solved_result = await solve_dependencies(
  File "fastapi/dependencies/utils.py", line 498, in solve_dependencies
    solved_result = await solve_dependencies(
  File "fastapi/dependencies/utils.py", line 523, in solve_dependencies
    solved = await solve_generator(
  File "fastapi/dependencies/utils.py", line 443, in solve_generator
    cm = asynccontextmanager(call)(**sub_values)
  File "contextlib.py", line 296, in helper
    return _AsyncGeneratorContextManager(func, args, kwds)
  File "contextlib.py", line 87, in __init__
    self.gen = func(*args, **kwds)

This error doesn't affect the application itself. It doesn't affect logic or request handling, but it's constantly appear in logs.

I use custom context like this:

from aio_pika import Channel
from aio_pika.pool import Pool
from aiokafka import AIOKafkaProducer
from fastapi import Depends
from redis.asyncio import Redis
from strawberry.fastapi import BaseContext

from testkaftemp.services.rabbit.dependencies import get_rmq_channel_pool
from testkaftemp.services.redis.dependency import get_redis_connection


class Context(BaseContext):
    """Global graphql context."""

    def __init__(
        self,
        redis: Redis = Depends(get_redis_connection),
        rabbit: Pool[Channel] = Depends(get_rmq_channel_pool),
    ) -> None:
        self.redis = redis
        self.rabbit = rabbit


def get_context(context: Context = Depends(Context)) -> Context:
    """
    Get custom context.

    :param context: graphql context.
    :return: context
    """
    return context

# In my router.py file
...
gql_router = GraphQLRouter(
    schema,
    graphiql=True,
    context_getter=get_context,
)

This works for handlers, but it throws an error when accessing graphiql page.

System Information

• Operating system: linux
• Python version: 3.9
• Strawberry version: 0.114.7

Additional Context

You can reproduce this issue easily by generating a project with FastAPI-template with graphql api type and with at least one dependency, such as redis.
