在嵌套的 Prisma / GraphQL 查询中找不到参数

Question

在我的 graphql-yoga 服务器中，我有这样的架构：

type Play {
  id: ID!
  frames: [Frame!]!
}

type Frame {
  id: ID!
  play: Play!
}

query  {
  play(playId: "myid") {
    id
    ### The error occurs when I uncomment these lines:
    # frames {
    #   id
    # }
  }
}

我有查询的解析器：

return await context.prisma.play({ id: args.playId })

我也有关系解析器，例如：

const frames = async (root, args, context) => {
  return await context.prisma.frames({ play: { id: root.id }})
}

当我运行带有注释行的查询时，它按预期执行。当我添加关系时出现错误：

Error: Could not find argument play for type Frame

    at server\node_modules\prisma-client-lib\dist\Client.js:22:71
    at new Promise (<anonymous>)

我正在使用prisma-client-lib@1.18.1、graphql-yoga@1.16.2 和graphql@0.13.0

事实证明，这个错误出现在解析器中，尽管堆栈跟踪没有帮助。我变了

const frames = async (root, args, context) => {
  return await context.prisma.frames({ play: { id: root.id }})
}

到

const frames = async (root, args, context) => {
  return await context.prisma.frames({ where: { play: { id: args.playId }}})
}
