I have Client<->Address relation defined in laravel as below

class Client extends Model
{
    use HasFactory;

    protected $keyType = 'string';

    public $incrementing = false;
    protected $fillable = [
        'name',
        'location',
        'status',
    ];

    public function address()
    {
        return $this->hasOne(ClientAddress::class);
    }
}

class ClientAddress extends Model
{
    use HasFactory;
    public $timestamps = false;
    
    protected $keyType = 'string';

    public $incrementing = false;
    
    protected $fillable = [
        'street',
        'zip',
    ];

    public function client()
    {
        return $this->belongsTo(Client::class);
    }
}

I am able to save it in database.
When I read it like below and print I get address

public function getAddress(Request $request)
    {
        $client=Client::with('address')->find($request->id);
        Log::info($client);
        Log::info($client->address);
        return ClientAddressResource::make($client->address);
    }

first log value is :

[2024-06-22 10:39:15] local.INFO: {“id”:”12cf02ff-fff7-4b8d-8eb5-64d5328afc8b”,”name”:”Client With address”,”location”:”Delhi”,”status”:”OK”,”address”:{“id”:”0b956710-3681-4042-96c2-877345167c46″,”street”:”str1″,”street2″:”str2″,”city”:”some city”,”state”:”stt”,”country”:”India”,”zip”:”1234″,”client_id”:”12cf02ff-fff7-4b8d-8eb5-64d5328afc8b”},”created_at”:”2024-06-20T21:14:50.000000Z”,”updated_at”:”2024-06-20T21:14:50.000000Z”}

second log is empty

[2024-06-22 10:39:15] local.INFO:

last line gives error

I tried a lot of google, and SO answers but none talks about reading of object and convert to json.
