4.3.0 typescript?

[compojoom]

I have this code:

import { Contract, EventLog, Receipt, Web3 } from "web3";
let web3Initialized: null | Web3 = null;
const getWeb3 = (): Web3 => {
  if (!web3Initialized) {
    web3Initialized = new Web3(
      process.env.REACT_APP_WEB3_PROVIDER_URL as string
    );
  }
  return web3Initialized;
};

and it is giving me this typescript error:

Type 'Web3<{ [key: string]: Web3SubscriptionConstructor<EthExecutionAPI>; }>' is not assignable to type 'Web3<RegisteredSubscription>'.
  The types of '_subscriptionManager.subscriptions' are incompatible between these types.
    Type 'Map<string, Web3Subscription<any, any, EthExecutionAPI, any>>' is not assignable to type 'Map<string, LogsSubscription | NewPendingTransactionsSubscription | NewHeadsSubscription | SyncingSubscription>'.
      Type 'Web3Subscription<any, any, EthExecutionAPI, any>' is not assignable to type 'LogsSubscription | NewPendingTransactionsSubscription | NewHeadsSubscription | SyncingSubscription'.
        Type 'Web3Subscription<any, any, EthExecutionAPI, any>' is not assignable to type 'SyncingSubscription'.
          Property '_buildSubscriptionParams' is protected but type 'Web3Subscription<EventMap, ArgsType, API, CombinedEventMap>' is not a class derived from 'SyncingSubscription'.ts(2322)
let web3Initialized: Web3<RegisteredSubscription> | null

What am I missing here? Why is the Web3 type not enough?
