Не удается вызвать функции из контракта с помощью web3.js

Итак, у меня есть Dapp, и я хочу вызвать функцию из контракта, развернутого на Rinkeby. Я использую Metamask для взаимодействия с блокчейном.

Когда я использую функции в консоли, они работают, но когда я хочу вызвать из JS-кода, они больше не работают. Мое Dapp работает на порту 3030.

Вот JS-код. Инициализация веб3:

import Web3 from 'web3';

export let web3;

if (typeof web3 !== 'undefined') {
  web3 = new Web3(web3.currentProvider);
} else {
  // set the provider you want from Web3.providers
  web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:3030'));
}

Вот файл .js с различными функциями:

import web3 from '../ethereum/web3.js';

      }

  }

}

export function notWeb3Connected() {

// Check the connection
if(!web3.isConnected()) {

  console.error("Not connected");

  return true;

}

return false;

}

А в другом файле я импортирую функции и записываю их результаты в консоль. Например, я делаю так:

import { getCurrentPublicAddress, getCurrentSPN } from '/imports/lib/pudding/manageSPN.js';

И это:

console.log(getCurrentAddress());
console.log(getCurrentSPN());

Когда я вызываю функции, они выдают ошибки:

PS: я использую метеор -p 3030 для инициализации моего приложения. PPS: с помощью getCurrentPublicAddress я получаю открытый ключ от Metamask. С помощью другой функции я получаю количество токенов, которые я отчеканил для этой конкретной учетной записи.
