Chapter 8 Auth and Deployment

Hello :) !
I started testing app after picture 8.3. 
(Firefox and Chrome)

After making purchases in the store, logging in to the administration panel, select the last page to find the orders placed, the following appears:

Unhandled Rejection (Error): GraphQL error: Cannot return null for non-nullable field order.name.

Best Regards I am waiting for the info;)
