Can't query interface types #414
Description
I have the following schema
interface Person { id: ID! name: String } type A implements Person { id: ID! name: String } type B implements Person { id: ID! name: String } When I run a query of the type:
query { Person { name } } I get the following error from the server.
Abstract type \"Person\" must resolve to an Object type at runtime for field \"Query.Person\" with value { name: \"A Person\", FRAGMENT_TYPE: null }, received \"null\". Either the \"Person\" type should provide a \"resolveType\" function or each possible type should provide an \"isTypeOf\" function. The full stacktrace is:
GraphQLError: Abstract type "Person" must resolve to an Object type at runtime for field "Query.Person" with value { name: "Giles Dring", FRAGMENT_TYPE: null }, received "null". Either the "Person" type should provide a "resolveType" function or each possible type should provide an "isTypeOf" function. at ensureValidRuntimeType (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:687:11) at completeAbstractValue (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:680:42) at completeValue (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:604:12) at completeValueCatchingError (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:514:19) at /Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:636:25 at from (<anonymous>) at completeListValue (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:632:49) at completeValue (/Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:592:12) at /Users/gilesdring/src/dringtech/eccoo/graph/api/node_modules/graphql/execution/execute.js:511:16 at processTicksAndRejections (internal/process/task_queues.js:97:5) This seems similar to a few other issues, but not exactly. I'm using v2.13.0. The way I'm reading the documentation, it should work.
