[Solved] SDK 3.0 initializer error

IN the unity editor thee ads work fine, but when i execute the app on android i allways get this error on the logcat

com.unity3d.services.core.api.Sdk.logError() (line:57) :: {}

.

I'm in unity 2018.2.18 and using unity ads sdk 3.0.

I use this code to initialize the ads:

Code (CSharp):

1.     string gameId = "XXXXXXX";
2.     bool testMode = false;
3.  
4.     void Start()
5.     {
6.         Monetization.Initialize(gameId, testMode);
7.     }

And this one to call the ads:

Code (CSharp):

1. [HideInInspector] public string whyIsRewarded;
2.  
3.     public void ShowRewardedAd(string why)
4.     {
5.         whyIsRewarded = why;
6.         StartCoroutine(WaitForAd());
7.     }
8.  
9.     IEnumerator WaitForAd()
10.     {
11.         while (!Monetization.IsReady("rewardedVideo"))
12.         {
13.             yield return null;
14.         }
15.  
16.         ShowAdPlacementContent ad = null;
17.         ad = Monetization.GetPlacementContent("rewardedVideo") as ShowAdPlacementContent;
18.  
19.         if (ad != null)
20.         {
21.             ad.Show(AdFinished);
22.         }
23.     }
24.  
25.     void AdFinished(ShowResult result)
26.     {
27.         if (result == ShowResult.Finished)
28.         {
29.             if (whyIsRewarded == "Continue")
30.             {
31.                 GameObject.Find("protected").SendMessage("Continue");
32.             }
33.             else if (whyIsRewarded == "Shop")
34.             {
35.                 GameObject.Find("CargarGuardar").SendMessage("AugmentCoins", Random.Range(10, 50));
36.             }
37.         }
38.         else
39.         {
40.             if (whyIsRewarded == "Continue")
41.             {
42.                 GameObject.Find("protected").SendMessage("NoContinue");
43.             }
44.             else if (whyIsRewarded == "Shop")
45.             {
46.                 Debug.Log("error");
47.             }
48.         }
49.     }

What i'm doing wrong?
How can i solve this?
