Hi, I have the same issue in Ionic 3 PWA.
The error happened when i do some action(click or navigate) after app was served
It happened once in a while, not everytime.
I have also deployed the app in firebase host.
This error will sometime show when i open the app.
I suspect this is problem of the service worker.
I have try @manoemerson, but its not work, the error remain, below is my service worker
This probably happen because something is not finish loaded, when i click a button, then error of Cannot read property ‘call’ of undefined
Anyone have solution for this?
Its not just happened in localhost, firebasehost also.
Randomly show up.
