Neo4j会话对象错误:结构(127，[[object .catch ]])

Question

当我在nodejs中执行这个命令时，我得到了一个.catch错误"catch error: structure (127，[object object])“。它在Neo4j浏览器中运行良好。有谁能解释一下这件事吗？我似乎找不到任何与这种类型的错误相关的信息。

session
  .run ("MERGE (user:Visitor {name:'Visitor', email : {paramEmail}})-[:SUBMITTED_RPA {since:timestamp()}]->(rpa:RPA {name: 'RPA', email:{paramEmail},rpa_id:{paramrpa_id}, makevehicle:{parammakeVehicle},vehicledescription:{paramvehicledescription},partdescription:{parampartdescription}}) RETURN user,rpa",
        { paramEmail: newUser.email,
          parammakevehicle: newUser.makevehicle,
          paramvehicledescription: newUser.vehicledescription,
          parampartdescription: newUser.partdescription,
          paramrpa_id: newUser.rpa_id
        })
