The error "Only arrays and Traversables can be unpacked" occurs when you try to access an element from an undefined or non-iterable variable.

In your code, the error is happening because the value of event.detail is not an array or a traversable object. The event.detail object seems to be an associative array, so you can directly access its properties using dot notation without unpacking it.

To fix the error, you need to update your JavaScript code and remove the [0] indexing from event.detail. Here's how you can modify your code:

window.addEventListener('Swal:DeletedRecord', event => {
  Swal.fire({
    title: 'Are you sure you want to delete this section: ' + event.detail.section_name + '?',
    text: event.detail.title,
    icon: 'warning',
    showCancelButton: true,
    confirmButtonColor: '#3085d6',
    cancelButtonColor: '#d33',
    confirmButtonText: 'Yes, delete it!'
  }).then((result) => {
    if (result.isConfirmed) {
      Livewire.dispatch('RecordDeleted', event.detail.id)
      Swal.fire(
        'Deleted!:',
        'Your file has been deleted.',
        'success'
      )
    }
  })
});

By removing the [0] indexing, you can access the properties directly from event.detail. Now, the section_name, title, and id should be properly passed to the ConfirmDelete method.

Additionally, to avoid the "undefined" value issue, make sure that the $sectionsdata variable in your controller contains the necessary data and is properly passed to the Blade view.
