Cannot connect to Alphadex (using adex.init())

[dcts]

I am trying to create a script to fetch volume data directly from the adex API, instead of updating it manually.

When I run this script:

/* eslint-disable no-console */
const adex = require("alphadex-sdk-js");

// call the init function to connect to the AlphaDEX exchange
// and initialize the clientState object
adex.init();

full script for reference: https://github.com/DeXter-on-Radix/website/pull/618/files

I get this error:
