/v1.2/requests/current returns curly braces for driver number

[hijklmno]

Hello team,

We recently ran into an issue when making the API call to /v1.2/requests/current via RidesService.getCurrentRide(). It seems the driver number sometimes return curly braces {} instead of String or null. Below is a scrubbed payload we received:

{
 "status": "in_progress",
 "product_id": "productId",
 "destination": {
 "latitude": 51.5405,
 "alias": "Home",
 "eta": 1,
 "longitude": -0.1336
 },
 "driver": {
 "phone_number": {},
 "rating": 4.92,
 "picture_url": "driverPhotoUrl",
 "name": "DriverName",
 "sms_number": null
 },
 "pickup": {
 "latitude": 51.5374,
 "region": {
 "latitude": 51.5126,
 "country_name": "United Kingdom",
 "country_code": "GB",
 "name": "London",
 "longitude": -0.1304
 },
 "longitude": -0.1414
 },
 "request_id": "requestId",
 "location": null,
 "vehicle": {
 "make": "vehicleMake",
 "picture_url": "vehicleUrl",
 "model": "vehicleModel",
 "license_plate": "licensePlate"
 },
 "shared": false
}

Here is the exception:

PlatformExceptionMapper:handleRuntimeException Unexpected runtime exception:
