hyperledger-fabric - 向 fabric-sdk-go 查询链码时出现恐慌

Question

我试图弄清楚 fabric-sdk-go 是如何工作的。我创建了与超级账本的连接，安装了链代码，但是当我出于某种原因尝试执行请求时出现错误。

我的功能：

response, err := setup.client.Query(channel.Request{ChaincodeID: setup.ChainCodeID, Fcn: "invoke", Args: [][]byte{[]byte("query"), []byte("hello")}})

和输出日志：

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x9384f0]

goroutine 1 [running]:
github.com/hyperledger/fabric-sdk-go/pkg/client/channel.(*Client).Query(0x0, 0xce8db5, 0x5, 0xce9c7d, 0x6, 0xc0001b1bd0, 0x3, 0x3, 0x0, 0x0, ...)

我跳过了通道连接设置步骤
