The flowing error is presented when calling keystore.generateRandomSeed

I am using Angular and before doing some JS libraries updates (Web3, EthLightWallet and many others), it was working.

I am not sure if this is related: Importing eth-lightwallet using (import { default as lightwallet } from 'eth-lightwallet';) no longer works. But the 'require' (declare let require: any; const lightwallet = require('eth-lightwallet');) works but introduced the mentioned error.
