Server does not receive full JS fix

I'm developing an application in Laravel, at a certain point I had to use an array of objects to store the information that is going to be sent to the server, the problem I'm having is that I build my array but at a certain point that the array is very large, not all information is sent to the server, even when the arrangement is well built.

This is the code I am using to send the information by ajax.

data: $('#account_status_form :not(.test_checkbox)').serialize() + '&' +
      $.param({
         binomios: nuevos,
         servicios_caballo: unique_horses,
         deleted_inscriptions: deleted_inscriptions,
         _token: '{{ csrf_token() }}'
      }),

The arrangement that is generated is something like this:

(43)[{
    active: "1",
    caballo_id: 1,
    caballo_nombre: "HIDALGO",
    jinete_id: "1",
    prueba_categoria_id: "1",
    …
}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]

That information comes in handy, but if I add a new object to the fix, the information of that last object does not come complete

Does anyone have any idea what the problem might be and how to fix it?
