Error when reference to lib/ionic-platform-web-client/dist/ionic.io.bundle.min.js

mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create ionic.io.bundle.min.js:2:7362

TypeError: this._settings is undefined ionic.io.bundle.min.js:2:9212

Same here, have you found a solution ?
