Error, missing Report Suite ID in AppMeasurement initialization

Starting with either AppMeasurement v2.2.0 or v2.3.0, when setting var s = new AppMeasurement(), AppMeasurement expects you to pass a parameter containing the RSID(s). If you exclude the parameter, you get the "missing report suite ID" message you are seeing.

I haven't researched the purpose or need for the new parameter enough to tell you why it is now "required," but I can confirm that passing the parameter gets rid of the message. I've tried passing in both invalid data (ie// "xxxx") and legitimate RSIDs ("ie// "mydevrsid" or "myprodrsid"), with both having the same result.

EDIT: A quick example:

var myrsid = (prod) ? "myprodrsid" : "mydevrsid";

var s = new AppMeasurement(myrsid);
