Bug Warning: openAdvertisingTrackingId with value: null

I'm developing a Flutter app and added Unity Ads through Admob mediation on Android. My device has an ad id and I allowed personalized ads. When running my app I see the following log:

W/UnityAds(12891): com.unity3d.services.core.api.Sdk.logWarning() (line:94) :: {"message":"model: DeviceInfo key: openAdvertisingTrackingId with value: null: null is not in: string,undefined","name":"CheckValueError"}

W/UnityAds(21336): com.unity3d.services.core.device.Device.getNetworkType() (line:152) :: Unity Ads was not able to get current network type due to missing permission

I would like to know what openAdvertisingTrackingId null means and how to fix it.

 

I have sent it now.

 

Did you solve this issue ?
