[Python] I have a problem with the parameters in fastapi

I have this application in fastapi. through a get request the page and area2 parameters are passed, the page parameter is correctly captured but the area2 is not, it returns none

<a href="?page={{ page_obj.number-1}}&?area={{area}}"> --previous </a>
{% endif %}
