i am building an app and I am using the Uber Java SDK in the Sandbox environment. The problem is the null returned from Uber for RideEstimate, Vehicle and Driver class.
Maven POM:

As you can see from the above, the RideEstimate, Vehicle and Driver classes all lead to null pointers. It is really strange that I can request a ride successfully without a Vehicle or Driver attached to the ride request. I found a workaround to get pass the RideEstimate returned as a null(see my code above) but I cannot find a workaround the Vehicle and Driver being null too.
So, if there is any other way to get the Vehicle and Driver being null, please inform me. Also, it would be nice to have some examples on using the Sandbox update status.
When you request a ride - it gets created with the "processing" state - and at this point, the driver is still unknown - because the driver did not accept this request yet. This is the reason why dont get any driver or vehicle info. The sandbox does not automatically move through a ride but you can manually put ride request through each state:
"Currently, the sandbox does not change states automatically the way a real request in production would. This endpoint gives the ability to walk an application through the different states of a ride request."
Please see the sandbox guide for more details: https://developer.uber.com/docs/riders/guides/sandbox.
To check Lifecycle of a Ride Request please read this documentation.
