Hello,
I am using the REST VRP endpoint to dispatch a fleet. I sent the request below with an order pair and set the assignment rule of one of the two stops to "anchor first. "

When I post this request to ArcGIS Online, I get the error below. why is it not possible to set the assignment rule to "anchor first" to one of the orders in a pair ?
Solver Failed with the following Warnings : ["type":"esriJobMessageTypeWarning","description":"Order Pairs
