Hyperledger fabric Query.js在Hyperledger FABCAR中工作不正常

我尝试在hyperledger fabric user1中执行fabcar示例时，已成功从持久性加载

执行query.js时出错导致此问题的原因是什么

下面我有详细的日志，并附上相同的截图清晰的图片

不确定hyperledger如何运行，但考虑到GRPC错误，您似乎连接到了错误的端口-您需要一个http/2端点，GRPC才能工作。如果您在端点前面运行自己的反向代理，也可能会发生这种情况。这是一个默认示例应用程序，取自Hyperledger。没有任何更改，初始的其他2个脚本已成功执行
