easyabp / abp.graphql Goto Github PK

Hello!
I followed step by step Abp.GraphQL instructions. Receiving the same exception when

1. Running the application and trying to use Playground UI (or simply navigating to my app /graphql route)
2. Running the built-in tests inside Abp.GraphQL solution
   The exception is:
   Autofac.Core.DependencyResolutionException
   An exception was thrown while activating EasyAbp.Abp.GraphQL.GraphQLAppService -> EasyAbp.Abp.GraphQL.Provider.GraphQLDotnet.GraphQLDotnetGraphQLQueryProvider -> λ:GraphQL.IDocumentWriter.
