TypeError: Cannot read properties of null (reading 'exists')

I get this error when trying to use this code and how do I fix it
import { HereWallet } from "@here-wallet/core";
const here = await HereWallet.connect();
const account = await here.signIn({ contractId: "social.near" });
console.log(Hello ${account}!);

I'm using nextjs

same, after clicking "connect here wallet" button
and what’s more interesting is that it worked for me in the morning without errors🤷‍♂️
