getEntitiesFromQuery fires warning upon item pickup

using script API, this is how to recreate.  

let serverSystem = server.registerSystem(0, 0);
let generalQuery = null;


// Setup which events to listen for
serverSystem.initialize = function () {
generalQuery = this.registerQuery();
}


// per-tick updates
serverSystem.update = function() {
let allEntities = this.getEntitiesFromQuery(generalQuery );
}

run this in the server.js and pick up any item including shot arrows.

You will get the "Script Error: Something went wrong".
