@nfacha @kxxxo Big apologies... I do not have much time to fix the bug my self right now, but I'll fix it as soon as i can.

Same error...
I need to change
$cluster = new MarkerCluster([
'jsonUrl' => Yii::$app->controller->createUrl('projects/json')
]);

for this:
$cluster = new MarkerCluster([
'url' => Yii::$app->urlManager->createUrl('projects/json')
]);

Because jsonUrl isn't throws this exception:
Setting unknown property: dosamigos\leaflet\plugins\markercluster\MarkerCluster::jsonUrl

and
Yii::$app->controller->createUrl('projects/json') throws: Calling unknown method: app\controllers\ProjectsController::createUrl()

but the error (Uncaught TypeError: Cannot read property 'trim' of undefined) don't fixed.

Finally, i added:
public $js = [
'https://unpkg.com/[email protected]/dist/leaflet.markercluster.js'
];
wich posted vladim1 in the other issue and works fine.
