Inappropriate response for error reporting during the migration of lwm2m devices

We have noticed an inappropriate response for error reporting during the migration of lwm2m devices in one of our customer tenancy.

• device count for migration success/failure is reported as null instead of actual count.

Customer attempted to migrate 2 devices(866416047975975 & 864700045057429) from connector device with below shell command.

migrateLwm2mDevices --devices 4660160670 4660158980

The above operation is failed with below response:

{
  "message" : "Devices not found or already migrated",
  "numberOfDevicesSuccessful" : null,
  "numberOfDevicesFailed" : null,
  "issues" : { }
}

Looking at the response -

"numberOfDevicesSuccessful" : null,

"numberOfDevicesFailed" : null,

"issues" : { }

Expected response:

"numberOfDevicesSuccessful" : 0

"numberOfDevicesFailed" : 2,

issues" : { } → possible reason for failure
