Redmine

I want to use the redmine-view-customize plugin to display pull-down custom fields.
The following code works in my local environment, but did not work when written to Redmine.
If there is an error in the code or the use of the plugin, please let me know.
I am having trouble understanding how to check the logs.

$(document).ready(function () {
    var parentField = 'issue_custom_field_values_1';
    var childField = 'issue_custom_field_values_2';

    var narrowChildField = function() {
          var optionList = [
            {parent: 36, children: [57, 59, 60, 20]},
            {parent: 42, children: [59, 61]},
            {parent: 43, children: [60]},
            {parent: 0, children: [57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 20]}
        ];

          var parentId = parseInt($('#' + parentField + ' > option:selected').data('select2-id'), 10);
          if (isNaN(parentId)) {
            console.error("Invalid Children ID.");
            return;
          }

          var selectedOption = optionList.find(o => o.parent === parentId);
        var childIds = selectedOption ? selectedOption.children : [];

          $('#' + childField + ' > option').each(function() {
            var childId = parseInt($(this).data('select2-id'), 10);
            if (isNaN(childId)) {
              console.error("Invalid child ID for option:", $(this).text());
              return;
            }

            if (childIds.includes(childId)) {
                  $(this).show();
            } else {
                  $(this).hide();
            }
          });
    };
    narrowChildField();

    $('#all_attributes').change(function(e) {
        if (e.target.id === parentField) {
            narrowChildField();
          }
    });

    if (typeof replaceIssueFormWith === 'function') {
        var _replaceIssueFormWith = replaceIssueFormWith;
        replaceIssueFormWith = function(html){
            _replaceIssueFormWith(html);
            narrowChildField();
          };
    }
});

Thank you in advance for your help.
