Hi Alberto,

Count is an operation that you perform on a mongo cursor. A findOne query will only ever return one result. If you're trying to get the length of the array use EXAMPLE.EX.length.

Hi Alberto,

Is the array "EX" inside of the object who's id is their playerId ? Your query looks wrong here. Currently its set up to find a document for that player that contains an empty array.

In test harness, "EX" returns this:

and thats stored in a runtime collection like this:

"EX":[{"testValue":03},{"testValue":23},{"testValue":00},{"testValue":03}{"testValue":03},{"testValue":45}]

Hi Alberto,

In that case use this as your query to find the document.

var EXAMPLE = Spark.runtimeCollection("RuntimeCollection").findOne({"_id": Spark.getPlayer().getPlayerId()});

Then use var COUNT = EXAMPLE.EX.length; to get the length.
