无法查询节点

Question

这是我的架构的结构

type Process @query(read: true, aggregate: true) {
  material_id: String
  batch_id: String
  basic_mat: String
  happened: Date
}

现在，查询过程返回一个空数组

query Processes($where: ProcessWhere) {
  processes(where: $where) {
    basic_mat
    material_id
    batch_id
  }
}

这是变量

{ 
  "where": {
    "batch_id": "abc101"
  }
}

我进一步启用调试，这就是我得到的

  @neo4j/graphql:auth using JWT provided in context: undefined +0ms
  @neo4j/graphql:execution executing cypher +0ms
  @neo4j/graphql:execution CALL dbms.components() YIELD versions, edition UNWIND versions AS version RETURN version, edition +1ms
  @neo4j/graphql:execution cypher params: {} +0ms
  @neo4j/graphql:translate ReadOperation
  @neo4j/graphql:translate |──── PropertyFilter [batch_id] <EQ>
  @neo4j/graphql:translate |──── AttributeField <basic_mat>
  @neo4j/graphql:translate |──── AttributeField <material_id>
  @neo4j/graphql:translate |──── AttributeField <batch_id> +0ms
  @neo4j/graphql:execution executing cypher +655ms
  @neo4j/graphql:execution MATCH (this:Process)
  @neo4j/graphql:execution WHERE this.batch_id = $param0
  @neo4j/graphql:execution RETURN this { .basic_mat, .material_id, .batch_id } AS this +0ms
  @neo4j/graphql:execution cypher params: { param0: 'abc101' } +0ms
  @neo4j/graphql:execution Execute successful, received 0 records +0ms

在 neo4j 中运行此密码会返回值，但当我使用 neo4j/graphql 库时不会返回值。 知道问题出在哪里吗

解决了，

需要将其添加到上下文中

 sessionConfig: { database: "myNeoGraph" }
