我正在尝试使用与Relay兼容的GraphQL架构设置node.js服务器.

尝试验证或加载架构时,我收到以下错误:

EventEdge.node field type must be Output Type but got: undefined.

这是由于在其他类型定义之一中为Event类型提供了连接类型.

我不会发布整个架构,因为它非常详细,但是当连接字段被注释掉时,架构被正确加载并且不会抛出任何错误.

我已经包含了导致相同问题的简化模式的示例:

  const graphql       = require('graphql')
  const relay         = require('graphql-relay')

  const GraphQLID         = graphql.GraphQLID,
        GraphQLInt        = graphql.GraphQLInt,
        GraphQLString     = graphql.GraphQLString,
        GraphQLList       = graphql.GraphQLList,
        GraphQLObjectType = graphql.GraphQLObjectType,
        GraphQLSchema     = graphql.GraphQLSchema,
        GraphQLNonNull    = graphql.GraphQLNonNull

  const connectionArgs               = relay.connectionArgs,
        connectionDefinitions        = relay.connectionDefinitions,
        connectionFromArray          = relay.connectionFromArray,
        cursorForObjectInConnection  = relay.cursorForObjectInConnection,
        fromGlobalId                 = relay.fromGlobalId,
        globalIdField                = relay.globalIdField,
        mutationWithClientMutationId = relay.mutationWithClientMutationId,
        nodeDefinitions              = relay.nodeDefinitions,
        toGlobalId                   = relay.toGlobalId

  // Models (ORM Mappings)
  const models = …
