Cannot get the JSON right in Laravel

For some reason i cannot get my content right while it seems identical i am missing something.

This is the hardcoded data i am using to compare my JSON output to:

$payload2 = '{
            "vehicles": [
                {
                    "vehicle_id": "my_vehicule",
                    "start_address": {
                        "location_id": "berlin",
                        "lon": 13.406,
                        "lat": 52.537
                    }
                }
            ],
            "services": [
                {
                    "id": "hamburg",
                    "name": "visit_hamburg",
                    "address": {
                        "location_id": "hamburg",
                        "lon": 9.999,
                        "lat": 53.552
                    }
                },
                {
                    "id": "munich",
                    "name": "visit_munich",
                    "address": {
                        "location_id": "munich",
                        "lon": 11.57,
                        "lat": 48.145
                    }
                },
                {
                    "id": "cologne",
                    "name": "visit_cologne",
                    "address": {
                        "location_id": "cologne",
                        "lon": 6.957,
                        "lat": 50.936
                    }
                }
            ]
        }';

And here is my built query:

        $currentDriverPositionLatitude = $currentDriverPosition['latitude'];
        $currentDriverPositionLongitude = $currentDriverPosition['longitude'];

        $services = [];

        $vehiculeUid = 'my_vehicule';
        $vehiculePositionUid = '2222-3333-4444-5555';
       
        $services1Id = 'location1Id';
        $services1Name = 'location1Name';
        $services1LocationId = 'location1Uid';
        $services1LocationLatitude = 4.8945;
        $services1LocationLongitude = 5.8945;
      
        $services2Id = 'location1Id';
        $services2Name = 'location2Name';
        $services2LocationId = 'location2Uid';
        $services2LocationLatitude = 6.8945;
        $services2LocationLongitude = 7.8945;
      
        $services3Id = 'location1Id';
        $services3Name = 'location3Name';
        $services3LocationId = 'location3Uid';
        $services3LocationLatitude = 8.8945;
        $services3LocationLongitude = 9.8945;
       
        $services1 = collect([
            "id" => $services1Id,
            "name" => $services1Name,
            "address" => collect([
                "location_id" => $services1LocationId,
                "lon" => $services1LocationLongitude,
                "lat" => $services1LocationLatitude,
            ])
        ]);
       
        $services2 = collect([
            "id" => $services2Id,
            "name" => $services2Name,
            "address" => collect([
                "location_id" => $services2LocationId,
                "lon" => $services2LocationLongitude,
                "lat" => $services2LocationLatitude,
            ])
        ]);

        $services3 = collect([
            "id" => $services3Id,
            "name" => $services3Name,
            "address" => collect([
                "location_id" => $services3LocationId,
                "lon" => $services3LocationLongitude,
                "lat" => $services3LocationLatitude,
            ])
        ]);
       
        array_push($services, $services1);
        array_push($services, $services2);
        array_push($services, $services3);

        $payload = collect([
            "vehicles" => [
                collect([
                    "vehicle_id" => $vehiculeUid,
                    "start_address" => collect([
                        "location_id" => $vehiculePositionUid,
                        "lon" => $currentDriverPositionLongitude,
                        "lat" => $currentDriverPositionLatitude,
                    ])
                ]),
            ],
            "services" => $services,
        ]);

The output is identical from what i can gather.
