Request keeps polling even with refreshInterval set to 0

[hydrohiester]

I was setting refreshInterval with a state variable that polls and when it gets a certain result, it is a dependency in a useEffect that sets the interval to 0. It kept polling even after the interval was set to 0. Then I tested, hard-coding the interval to 0 and it still keeps making requests. Why would this be happening?

const fetcher = async (url: string) => { return fetch(url, { method: "GET", headers: { Authorization:Bearer ${token}`,
},
}).then((res) => res.json());
};

const { data, error } = useSWR(
/api/my/endpoint,
fetcher,
{ refreshInterval: 0 }
);`
