Answer 1

Hi I solved adding $value = array() in line 287.
if (empty($value)) {
$value = array();
$value['formId'] = $form_id;
if (!empty($repeater_start)) { $value['start'] = $repeater_start; }
if (!empty($repeater_min)) { $value['min'] = $repeater_min; }
if (!empty($repeater_max)) { $value['max'] = $repeater_max; }
if (!empty($repeater_children)) { $value['children'] = $repeater_children; }
$value = json_encode($value);
}
That's work for me, I hope it could help you.
