Nodejs - ERR_TLS_CERT_ALTNAME_INVALID - node.js

Question

I have called this function below:
export async function getStaticProps() {
const res = await fetch("https://links.papareact.com/pyp");
const exploreData = await res.json();
return {
props: {
exploreData,
},
};
}
And it is showing the error below. How do I solve this issue?
Server Error
FetchError: request to https://jsonkeeper.com/b/4G1G failed, reason: Hostname/IP does not match certificate's altnames: Host: jsonkeeper.com. is not in the cert's altnames: DNS:www.jsonkeeper.com
This error happened while generating the page. Any console logs will be displayed in the terminal window.

I was trying to call an api but its showing
type: 'system',
errno: 'ERR_TLS_CERT_ALTNAME_INVALID',
code: 'ERR_TLS_CERT_ALTNAME_INVALID',
I have installed mkcert but the problem was not solved.

You just need to add www to the jsonkeeper link
export async function getStaticProps() {
const res = await fetch('https://www.jsonkeeper.com/b/4G1G');
const exploreData = await res.json();
return {
props: {
exploreData,
},
};
}
