    e.preventDefault();

having a different amount of hooks will break react, it tracks the order the hooks were called to identity them- https://legacy.reactjs.org/docs/hooks-rules.html#:~:text=Only%20Call%20Hooks%20at%20the%20Top%20Level&text=Instead%2C%20always%20use%20Hooks%20at,each%20time%20a%20component%20renders. If you want to conditionally get data, call useQuery top level, and use the enabled property to control the request. Or you can use .refetch(), but this option will always cause a new request, even if your cache has data
