Polygons are marked on the map in an old version of leaflet, but they do not work when updating the version

// This is a summarized example of the $map_features array I'm using: $map_faetures = [ 0 => [ "type" => "polygon", "weight" => 1, "points" => [ 0 => [ "lat" => "-31.60556406", "lon" => "131.535899285", ], 1 => [ "lat" => "-31.727797133", "lon" => "-31.727797133", ], 2 => [ "lat" => "-31.82398854", "lon" => "131.923106316", ], // ..., ], ], 1 => [ "type" => "polygon", "weight" => 2, "points" => [ // ... ], ], // ..., ]; // MyMap is defined in the mymodule_leaflet_map_info() implementation. $map_info = $map_info = \Drupal::service('leaflet.service') ->leafletMapGetInfo()['myMap']; $height = '450px'; // $map = \Drupal::service('leaflet.service')->leafletRenderMap($map_info, $map_features, $height);

Investigating the problem I realized that the following error was being displayed in the DevTools console

drupal.js?v=10.2.4:64 Uncaught TypeError: Cannot read properties of undefined (reading 'include_path')

On line 525 of the file leaflet/js/leaflet.drupal.js :

lFeature = this.create_polygon(feature, map_settings ? map_settings['leaflet_markercluster']['include_path'] : false);

An error occurs if $map_settings['leaflet_markercluster'] does not have a value.

Fix the problem by adding 'leaflet_markercluster' => ['include_path' => FALSE, 'control' => FALSE], in 'mymap' configuration.

function my_modulo_leaflet_map_info() {
  return [
    'MyMap' => [
      'label' => 'My Map',
      'description' => t('My map'),
      'settings' => [
        'center' => [
          'lat' => '-40.41',
          'lon' => '-64.69',
        ],
        'dragging' => TRUE,
        'touchZoom' => TRUE,
        'scrollWheelZoom' => TRUE,
        'doubleClickZoom' => TRUE,
        'zoomControl' => TRUE,
        'attributionControl' => TRUE,
        'trackResize' => TRUE,
        'fadeAnimation' => TRUE,
        'zoomAnimation' => TRUE,
        'closePopupOnClick' => TRUE,
        'layerControl' => TRUE,
        'layerControlOptions' => [
          'position' => 'topright',
        ],
        'leaflet_markercluster' => ['include_path' => FALSE, 'control' => FALSE],
      ],
      'layers' => [
        'earth' => [
             // ...
          ],
        ],
      ],
      'plugins' => [],
    ],
  ];
}

I think this should not be a required parameter.
