The status occurs when in a Push API call in object TO defined filter which doesn’t resolve any pushRegistrationIds as destinations for Push delivery. Field to is used to query the message recipient segment. For example, you can try to target according to a “tag” which doesn’t exist at any of instances of the requested ApplicationCode; it will return no destinations as we couldn’t find anything that would satisfy the requested conditions in our database. In another example, you may want to target all application instances (devices) with the Android OS. In this case, you have to use CloudType: GCM and API internally will resolve all destinations and will send the message to all Android devices linked to the requested ApplicationCode. You can also check your valid registrations by using filtering in our web interface. You can more information about User Data at our SDK pages:iOSandAndroid.

The status occurs when an invalid or non-existent ApplicationCode is used in the field from in a Push API call. Each application profile has its own unique ApplicationCode. ApplicationCode is used in SDK as a key identifier for the Application installed on an end user’s device able to communicate with our platform. For the paired device + installed app, pushRegistrationId is issued and it is uniquely linked to ApplicationCode. You should be able to get all available applications or check the configuration.
