Ionic Framework ionic-v3
1

Hello everyone, i need some help with my ionic projet.
I use Youtube Api to get a video Id and then open the video with InAppBrowser plugin.

It’s works with my browser and the ionic dev app. But not when i build my ipa file and run it on my ios device.

My configuration :

Ionic:

   ionic (Ionic CLI)  : 4.7.1 (/usr/local/lib/node_modules/ionic)
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.1

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : ios 4.5.5
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 3.1.2, (and 9 other plugins)

System:

   ios-deploy : 1.9.4
   NodeJS     : v10.15.0 (/usr/local/bin/node)
   npm        : 6.4.1
   OS         : macOS Mojave
   Xcode      : Xcode 10.1 Build version 10B61

My provider :

public fetchTrailer(mediaTitle: string) {
    console.log("IN FETCH");
    
    let searchText: string = mediaTitle + " bande annonce";
    let url: string = YOUTUBE_API_URL +"search?maxResult=" +"1" +"&key=" +YOUTUBE_API_KEY +"&part=snippet&q=" +searchText;
    console.log("URL " + url);
    return new Promise (resolve => {
      this.http
      .get(
        YOUTUBE_API_URL +
        "search?maxResult=" +
        "1" +
        "&key=" +
        YOUTUBE_API_KEY +
        "&part=snippet&q=" +
        searchText
      ).subscribe(
        data => {
          resolve(data);
      },
      err => {
        console.log(err);
      }
      );
    });
  }

Xcode console error :

{"headers":{"normalizedNames":{},"lazyUpdate":null,"headers":{}},"status":0,"statusText":"Unknown Error","url":null,"ok":false,"name":"HttpErrorResponse","message":"Http failure response for (unknown url): 0 Unknown Error","error":{"isTrusted":true}}

Thanks a lot
