App Center SDK not working on an Ionic Cordova App

Question

We are trying to use App Center SDK in an Ionic Cordova app.
We get the below error when we start the app

startService:withAppSecret:transmissionTargetToken:fromApplication:]/398 Cannot start service MSCrashes. App Center was started without app secret, but the service requires it.

We are putting the APP_SECRET in the config.xml. Is this version related?
