[SingleQueryHandler]：评估：消息=查询失败错误：[]，stack=FabricError：查询失败错误：[] Hyperledger Fabric SDK 2.2

分类：编程问答

如何解决[SingleQueryHandler]：评估：消息=查询失败错误：[]，stack=FabricError：查询失败错误：[] Hyperledger Fabric SDK 2.2

我正在运行 Fabric Node SDK 2.2。我在查询分类帐时面临的问题是这样的。

error: [SingleQueryHandler]: evaluate: message=Query failed. Errors: [],stack=FabricError: Query failed. Errors: []
    at SingleQueryHandler.evaluate (/fabric23/node_modules/fabric-network/lib/impl/query/singlequeryhandler.js:47:23)
    at Transaction.evaluate (/fabric23/node_modules/fabric-network/lib/transaction.js:276:49)
    at ContractImpl.evaluateTransaction (/fabric23/node_modules/fabric-network/lib/contract.js:179:45)
    at main (/fabric23/test.js:69:40)
    at processTicksAndRejections (internal/process/task_queues.js:97:5),name=FabricError
Failed to evaluate transaction: FabricError: Query failed. Errors: []

所以我设置了调试日志位置，发现 singlequeryhandler.js 构造函数正在传递一个空的 peers 列表。但是在此之前，日志显示它能够连接到网络中的所有对等节点和排序节点。不确定我是否做错了什么。在构造函数日志行周围添加 *s 以使其可见。
