Ajax data not getting into controller - ajax

Question

I am using an ajax request to show some information, on my local development version it works perfectly, but on the production server (Ubuntu 16.04 LEMP) it fails in validation, because there is no data in the request.
Checks
The url is correctly showing (e.g. example.com/employeeInfo?employeeId=1)
Ajax itself is working: when I hard-code the controller's response everything is fine.
I cannot figure out why this happens in production, but not on the local version... Huge thanks for any clues!
View
<script>
(function ($) {
$(document).ready(function() {
$(".team-pic").off("click").on("click", function() {
var employeeId = $(this).data('id');
// Get data
$.ajax({
type: "GET",
url: "employeeInfo",
data: {employeeId:employeeId},
success: function(data){
var obj=$.parseJSON(data);
$('#team-info-title').html(obj.output_name);
$('#team-info-subtitle').html(obj.output_role);
$('#resume').html(obj.output_resume);
$('#linkedin').html(obj.output_linkedin);
$("#team-info-background").show();
$("#team-info").show();
}
});
});
});
}(jQuery));
</script>
Route
Route::get('/employeeInfo', 'EmployeeController#getInfo');
Controller
public function getInfo(Request $request) {
if($request->ajax()) {
$this->validate($request, [
'employeeId' => 'required|integer',
]);
$employee = Employee::find($request->employeeId);
$output_linkedin = '<i class="fab fa-linkedin"></i>';
$data = array("output_resume"=>$employee->resume,"output_linkedin"=>$output_linkedin, "output_name"=>$employee->name, "output_role"=>$employee->role);
echo json_encode($data);
}
}

If you want to pass a get data employeeId you have to pass a slug through your route either you should pass the data by POST method.
Route::get('/employeeInfo/{slug}', 'EmployeeController#getInfo');
And Get the slug on your function on controller .
public function getInfo($employeeId)
