Good afternoon i will continue here my old post, I have a small problem, I have 2 different functions and then I can share them, but in my code what is happening is that one of these lines of code works, and the other doesn’t, and I really wanted to know why , because I wanted to insert a uuid in the cookies, but it didn’t, just another way, here it goes:

something like, this one works:
response.set_cookie('user_uuid', str(face_recognition.uuid))

but this one no response.set_cookie('user_uuid', str(cookie_uuid))

why ? no idea, they have the same value and the same name, one insert , and the other one no

the code that doesn’t work

def unique_identifier(request):
    print("unique identifier function called...")
    response = HttpResponse("Cookie Set")
    cookie_uuid = uuid.uuid4() # Create a UUID
    response.set_cookie('user_uuid', str(cookie_uuid))
    print("UUID defined in the user's cookies:", cookie_uuid)
    return response

debug:

No UUID found in user cookies
created a new UUID.
