字段级密码语句在接受阿波罗服务器中的参数时不工作。

Question

字段级的cypher指令不像期望的那样工作。

最起码的例子：

type Question {
  id: ID! @id
  required: Boolean
  testing(someId: ID!): Boolean
    @cypher(statement: """
      MATCH (q:Question {id:$someId}) RETURN q.required
    """)
}

当运行下面的查询时，我会得到一个错误。

{
  Question {
    testing(someId: "12345678-1234-1234-1234-0123456789ab")
  }
}

这是在阿波罗游乐场中看到的错误日志：

我的package.json包括以下版本：

"apollo-server": "^2.25.0",
"apollo-server-core": "^2.25.0",
"graphql-tag": "^2.12.5",
"neo4j-driver": "^4.3.1",
"neo4j-graphql-js": "^2.19.2",

顶级查询(带有参数)和带密码装饰器的字段级查询工作良好，只要这些查询不接受参数。我当时的印象是，这件事以前起过作用。

除非创建突变，否则库"neo4j-graphql-js": "^2.19.2"似乎不会传递自定义参数。尝试以下方法：

type Question {
  id: ID! @id
  required: Boolean
}

extend type Mutation {
  testing(someId: ID!): Boolean
    @cypher(
      statement: """
      MATCH (q:Question {id: $someId}) RETURN q.required
      """
    )
}

mutation {
  testing (someId: "12345678-1234-1234-1234-0123456789ab") 
}
