I have a problem, when I run Rewarded ad in my application, I get a NullReferenceException: Object reference not set to an instance of an object.
private RewardBasedVideoAd rewardBasedVideo;

public void Start()
MobileAds.Initialize(initStatus => { });

this.rewardBasedVideo = RewardBasedVideoAd.Instance;


this.rewardBasedVideo.OnAdLoaded += this.HandleRewardBasedVideoLoaded;
this.rewardBasedVideo.OnAdFailedToLoad += this.HandleRewardBasedVideoFailedToLoad;
this.rewardBasedVideo.OnAdOpening += this.HandleRewardBasedVideoOpened;
this.rewardBasedVideo.OnAdStarted += this.HandleRewardBasedVideoStarted;
this.rewardBasedVideo.OnAdRewarded += this.HandleRewardBasedVideoRewarded;
this.rewardBasedVideo.OnAdClosed += this.HandleRewardBasedVideoClosed;
this.rewardBasedVideo.OnAdLeavingApplication += this.HandleRewardBasedVideoLeftApplication;

private void RequestRewardBasedVideo()
string adUnitId = "ca-app-pub-3940256099942544/5224354917";

AdRequest request = new AdRequest.Builder().Build();
this.rewardBasedVideo.LoadAd(request, adUnitId);

public void UserOptToWatchAd()
if (rewardBasedVideo.IsLoaded())
I did everything as in the google guide, but I get this error. If you click on it, it takes you to the line "if (rewardBasedVideo.IsLoaded())". Please help me fix it

What version of the plugin do you have in unity?


For plugin versions 3.16.0 or higher, you must write the code differently instructions .

NULL, it means there is no object. That is, during the check, you are asking the object, which is NULL, what its state is. This is the error.

Why it's not there - read the script, figure out what you missed and where.
