Request object isn't passed as argument

Thanks for this package. I have created graphql app using template but getting below error. It seems fastapi doesn’t pass request object.

Until this is issue is solved, you can get rid of the error messages by changing the dependency slightly:

 async def get_db_session(request: Request = None) -> AsyncGenerator[AsyncSession, None]: 
     """ 
     Create and get database session. 
  
     :param request: current request. 
     :yield: database session. 
     """ 
     if request is None:
         yield None
         return

     session: AsyncSession = request.app.state.db_session_factory() 
  
     try:  # noqa: WPS501 
         yield session 
     finally: 
         await session.commit() 
         await session.close()

Hi there. I found no issues for this problem in strawberry-graphql repository. So I created one.
