I’m just starting to try out Auth0 with Cordova and downloaded and attempted to run the example quick start for my app. At first I was getting an Object.assign is not function so I modified the example webpack config to be: [‘babel-polyfill’, ‘./src/index.js’] and also installed babel-polyfill as a dev dependency.
The app will now load and run but when being redirected back to the example app from the Auth0 site, I’m getting a “net::ERR_UNKNOWN_URL_SCHEME”. I’m currently trying to run this on an Android tablet emulator running Android Marshmallow 6.0.
To reproduce this error create a native app in the Auth0 Dashboard, download the quickstart, follow the instructions to try to run it, modify the webpack config, install babel-polyfill, and then re-build and run the app.
