calling PlayerEnterColshape Event on Javascript Serverside doesn't work if c# is enabled

[Joto65]

Two different js scripts, which work fine if C# is disabled, suddenly stopped working when I enabled c# to use salty-voice.
Error Message in Console: "Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.at void Bootstrapper.EventInternalClass.OnPlayerEnterColshape(ushort playerId, ushort colshapeId)"
 

the code in one of the js files:
mp.events.add("playerEnterColshape", (player, shape) => {
    if (shape.clothingShopType && typeof player.clothingShopType !== "string") player.clothingShopType = shape.clothingShopType;
});
