I am on Unity and I'm trying to run the SampleScene, but I am getting error in description

NullReferenceException: Object reference not set to an instance of an object
BNB.BanubaSDKManager.processCameraImage (BNB.BanubaSDKBridge+bnb_bpc8_image_t cameraImage)

Also the Recognizer is always null.

Errors similar to the above are more often than not the result of either the token being posted incorrectly in the corresponding file (typos, spaces, cutoff symbols), or the token being incorrect.

Please contact your assigned Banuba Sales Department Representative and ask them to issue a new token for you that for the Face AR SDK and your development and target platforms.
