Get repeatable json data in Request select_from_ajax - laravel-backpack

Question

I have a repeatable field --and others-- with an ajax select inside. It has an endpoint route. In the controller of the route i do this
$inputs = $request->input('form');
dd($inputs);
It show all form fields that were completed except the repeatable field. Like this
6 => array:2 [
"name" => "payment_method"
"value" => 1
]
7 => array:2 [
"name" => "date"
"value" => "2020-12-17"
]
8 => array:2 [
"name" => "expiration"
"value" => "2020-12-31"
]
9 => array:2 [
"name" => "invoice_lines_data" <------- repeatable field
"value" => null <---- HERE THE JSON DATA
]
I want the actual json value of the repeatable field. Any help? Thanks

Update $(element).select2 function of select2_from_ajax.blade.php with the following code.
var formSerializeArray = form.serializeArray();
let rowNumber = element.attr('data-row-number');
let selector = element.attr('data-custom-selector');
// if any dependencies have been declared inside repeatable field
// then send those dependencies value with ajax fetch request
for (var i=0; i < $dependencies.length; i++) {
var $dependency = $dependencies[i];
//if element does not have a custom-selector attribute we use the name attribute
if(typeof element.attr('data-custom-selector') != 'undefined') {
// we get the row number and custom selector from where element is called
let rowNumber = element.attr('data-row-number');
let selector = element.attr('data-custom-selector');
// replace in the custom selector string the corresponding row and dependency name to match
selector = selector
.replaceAll('%DEPENDENCY%', $dependency)
.replaceAll('%ROW%', rowNumber);
console.log(selector)
dependency_val = $(selector).val();
if(dependency_val){
formSerializeArray.push({name: $dependency, value: dependency_val});
}
}
}
return {
q: params.term, // search term
page: params.page, // pagination
form: formSerializeArray
//form: form.serializeArray() // all other form inputs
};
