After creating a new View which renders a Leaflet map, it is not possible to edit the map settings in the view. An ajax error is thrown in the console.
The following error is thrown: Warning: Undefined array key \"weight\" in /var/www/html/web/modules/contrib/leaflet/src/LeafletSettingsElementsTrait.php on line 418
After investigation, there is no value weight set in the getDefaultSettings() function, if the weight value is missing. Attached patch fixes this problem.

Thanks @mrcdrx ... nice catch.
This last commit https://git.drupalcode.org/project/leaflet/-/commit/e4499518816dd52dc98c... implements your patch but with a better positioning of the 'weight' default value in the array.
Closing this as fixed (and crediting you).
