Twilio Conversations twilsock.InitRegistration() is not a constructor

Given this, im getting this output…

import { Client } from '@twilio/conversations';

... crap....

this.client = new Client(this.token);
      this.client.on('stateChanged', state => {
        if (state === 'initialized') {
          this.ready = true;
          this.emitter.emit('ready');

... more stuff....

I’ve stopped the debugger at that line and this is the value of twilsock on that line… any suggestions?
