How to get multiple trackers to work using @redux-beacon/google-analytics?

I'm using redux-beacon and google-analytics in my project to track ecommerce events in two Google Analytics-accounts. As not all data is coming through in the reports I'm trying to debug where it goes wrong using the Google Analytics Debugger Chrome Extension. It seems that all calls throw a 'Set called on unknown field: "customTrackerId".' Has anybody come across this before?

import {
  trackEcommProduct,
  trackEcommAction,
  trackPageView,
  trackEvent
} from '@redux-beacon/google-analytics';

export const CLIENT_TAG = 'client';

const getLocation = () => window.location.href;
const getPage = () => getLocation().split('#')[1];

export const clientPageView = trackPageView((action, prevState, nextState) => ({
  location: getLocation(),
  page: getPage(),
  title: action.title
}), CLIENT_TAG);

Pasting the events on the console spit by the chrome extension:

Solution

Thanks for pointing this out. This looks to be an issue on our end. The trackPageView event helper adds a customTrackerId property to the event to allow us make hits with a given tracker id (or set of tracker ids). There's no need for this property to exist outside redux-beacon so I've just parsed it out of any outgoing events. I've published a new version of the google-analytics target:

npm install @redux-beacon/[email protected]

Give it a go, and let me know if it fixes your issue!
