Question

我正在使用带有Prisma的Graphql服务器。但是当我尝试运行代码时出现此错误我正在使用

    SELECT 
      fullVisitorId,
      visitNumber,
      (SELECT max(case when customdimension.index = 16 then customdimension.value else '' end) as cd_16,
      (SELECT max(case when customdimension.index = NN then customdimension.value else '' end) as cd_NN
    FROM ga_sessions

这是错误

const { GraphQLServer } = require('graphql-yoga')
const { prisma } = require('./generated/prisma-client')

我试图从数据模型中删除约束，但错误仍然存在

Error: Directive constraint: Couldn't find type constraint in any of the schemas.

at new GraphQLServer (D:\project\Starter\server\node_modules\graphql-yoga\dist\index.js:95:34)

有人有相同或相似的错误吗？谢谢

我找到了解决此问题的方法最后，这是一个打字问题，该指令未声明，因此graphql-yoga无法识别该指令，因此我在包含所有实体声明的schema.graphql文件中添加了该指令的声明

directive @constraint(
  maxLength:Int!
) on FIELD_DEFINITION

所以在这里graphql-yoga可以找到该指令。希望对您有帮助我不知道它是如何从内部工作的，但是它解决了我的问题

错误：使用约束时Graphql Yoga中的指令约束
