[solved] Ionic 3 - Cannot read property 'get' of undefined


I do not understand why the get property from storage is not found.

I get the json file from my service and I store it in local storage to use it in the tab page. I call the service from my tabs (manager) page. When I go to the page I load the data from storage.

core.js:1449 ERROR Error: Uncaught (in promise): TypeError: Cannot read property ‘get’ of undefined.

class pointer is unknow when call by the rx observer
