Ad Errors

When an error occurs during ad loading or rendering, a callback providing a GfpError is invoked.

When using GfpAdLoader to load ads, the onError() callback of the AdEventListener set via withAdListener() is called to handle the error.

Kotlin

val adLoader = GfpAdLoader.Builder(this, adParam)
    ...
    .withAdListener(object : AdEventListener() {
        ...

        override fun onError(error: GfpError, responseInfo: GfpResponseInfo?) {
            // Called when an error happened while the ad is
            // attempting to load or rendering an ad.
        }
    })
    .build()

Java

GfpAdLoader adLoader = new GfpAdLoader.Builder(this, adParam)
    ...
    .withAdListener(new AdEventListener() {
        ...

        @Override
        public void onError(GfpError error, GfpResponseInfo responseInfo) {
            // Called when an error happened while the ad is
            // attempting to load or rendering an ad.
        }
    })
    .build();

The following shows the format of the error information provided when an error occurs during ad loading or during the rendering process after loading.

Kotlin

override fun onError(error: GfpError, responseInfo: GfpResponseInfo) {
    // Gets a GfpErrorType enum indicating the type of error.
    val errorType = error.errorType

    // Gets an error code specific to the errorType.
    val errorCode = error.errorCode

    // Gets a string representing the detailed error sub-code.
    val errorSubCode = error.errorSubCode

    // Gets an error message.
    val errorMessage = error.errorMessage

    // Gets additional response information about the request.
    Log.d("NamAds", responseInfo.toString())

    // All of this information is available using the error's toString() method.
    Log.d("NamAds", error.toString())
}

Java

@Override
public void onError(GfpError error, GfpResponseInfo responseInfo) {
    // Gets a GfpErrorType enum indicating the type of error.
    GfpErrorType errorType = error.getErrorType();

    // Gets an error code specific to the errorType.
    int errorCode = error.getErrorCode();

    // Gets a string representing the detailed error sub-code.
    String errorSubCode = error.getErrorSubCode();

    // Gets an error message.
    String errorMessage = error.getErrorMessage();

    // Gets additional response information about the request.
    Log.d("NamAds", responseInfo.toString())

    // All of this information is available using the error's toString() method.
    Log.d("NamAds", error.toString());
}

Common Error Logging Messages Debugging

errorMessage	Description	Solution
Empty render type	No ad was returned due to insufficient inventory, or a mediation network dependency is missing, making it impossible to find a usable mediation adapter.	Contact the NAM administrator.
There is no adapter available or Not found adapter: xxx, xxx, xxx, xxx	NAM SDK could not find a usable mediation adapter.	1. Add the missing mediation adapter to the project. 2. Verify that the ad is being loaded with the correct adUnitId for the ad format.
Network failed to respond in a timely manner	Ad request timeout.	1. Improve the internet connection and retry. 2. Adjust the request timeout globally or for specific ad formats.
MediaRenderer is required	The native ad response does not include media assets.	1. Since this is a native ad that does not require a media view, remove GfpMediaView when defining GfpNativeAdView. 2. When configuring GfpNativeAdOptions, explicitly set false as the argument for setHasMediaView() to request a native ad without a media view.
Bid 421...586 for template 200 being used on template NATIVE_BANNER	Unable to process Meta(FAN) native banner ads.	1. Verify in Meta Admin that the unit type is Native Banner. 2. When configuring GfpNativeAdOptions, ensure that setHasMediaView(false) is set to allow the use of Native Banner.
No ad config	Google Ad Manager(DFP) configuration issue.	Check the Google Ad Manager Admin.
