Ionic 2 limit the page name?

Hello, there is a limit to the name of a page?
Today, I faced a problem when the name of my page was very large.
my home.html:

    <button secondary block large round (click)="goToBackGroundGeolocation()">
      <ion-icon name="ios-navigate-outline"></ion-icon>

my old home.ts:


Only worked when I changed the page name
my new home.ts:


Any chance a reference to the longer name had a typo in it? LongStudlyCapsCaseNames are particularly prone to inconsistencies in capitalization.

It was typo.
this was my import:

import {BackGroundGeolocationPage} from "../back-ground-geolocation/back-ground-geolocation";
