     47   From the graqhql schema specification
     48 
     49   A GraphQL schema includes types, indicating where query and mutation
     50   operations start. This provides the initial entry points into the type system.
     51   The query type must always be provided, and is an Object base type. The
     52   mutation type is optional; if it is null, that means the system does not
     53   support mutations. If it is provided, it must be an object base type.
