@libra146 Additionally if your cookie’s key is something like X-Token (with a dash in it), you need to read it as x_token

@mattholy I also encountered this problem, can you provide some help, thank you

Your variable’s name must be the same as your cookie’s key e.g. in the example I provided above if you would like to read fakesession in cookies you have to make your code be like :

async def read_items(fakesession: Optional[str] = Cookie(None)):
    return {"whatever": fakesession}
