Unable to get FAN ads in android



I am trying to integrate FAN native ads with Mopub. I follow the process according to documentation. But I am unable to get any test ads from FAN.
I got the below error from Logcat.

D/FBAudienceNetworkLog: Audience Network Loaded (displayed for test ads only)
Native Ad failed to load with error: A required renderer was not registered for the CustomEventNative…

Native ad request failed.
com.mopub.network.MoPubNetworkError: No ads found for ad unit.
