Failing to use node-ic0

Developers

my js code:

import { ic} from "ic0";
import pkg from '../src/declarations/issuance_canister/issuance_canister.did.js';
const { idlFactory } = pkg;

const issuance_canister = ic.local('rrkah-fqaaa-aaaaa-aaaaq-cai');
// const res = await issuance_canister.call('query_authority');
console.log(issuance_canister)

error:

also, can I use a different caller to call the functions?
if yes, can I get some examples?
