Unable to use Wallet in thetajs

[the-xperimentalist]

Hello, posting here since couldn't find theta js repository.
I am following the Get Started tutorials of theta js. And am unable to import all the objects, as required. The following is the initial code:

import './style.css'
import * as THETA from "@thetalabs/theta-js";

console.log(THETA)

const provider = new THETA.providers.HttpProvider()

const privateKey = "0x0000000000000000000000000000000000000000000000000000000000000000"
const wallet = new THETA.Wallet(privateKey)

console.log(wallet)

Here, I am getting the following error in the line where the wallet is created:

Uncaught TypeError: can't access property "fromRed", this.x is null

    _encode thetajs.umd.js:37078

My package json dependencies are:

I am using webpack for working on the page right now. Don't think that should cause an issue. Please let me know
