Fabric SDK Go-尝试进行查询时过滤器排除对等项

我试图在实例化我的链码后执行以下语句：

response, err := client.Query(channel.Request{
    ChaincodeID: heligo.fsConfig.ChainCodeID,
    Fcn: "invoke",
    Args: defaultQueryArgs},
    channel.WithRetry(retry.DefaultChannelOpts),
)

但是我收到以下调试日志错误：

我无法弄清楚为什么我的同伴被排除在外，我正在修改BYFN示例项目并添加自己的链码。

我确实尽力去解决这个问题，但是由于文档不够深入，我还是没办法。任何帮助是极大的赞赏！！

答案 0 :(得分：1)

问题是实体匹配器部分中的urlSubstitutionExp和eventUrlSubstitutionExp的值错误。值应该是对等名称，而不是localhost。
