hyperledger-fabric - 如何修复 Hyperledger Fabric 中的 "rpc error: code = Unknown desc = access denied: channel [mychannel] creator org [Org1MSP]"错误

Question

目前我正在使用 Hyperledger Fabric 1.4，我正在尝试修改基础网络。我正在尝试与一个对等方一起添加 org2。每当我尝试从第二个组织 (Org2) 的对等方调用链代码时，我都会收到以下错误:

错误:背书链代码时出错:rpc 错误:代码 = 未知描述 = 访问被拒绝: channel [] 创建者组织 [Org2MSP]

我当前的网络组件是:
org1，有两个同行
org2，有一个同行
CA1
CA2
订单
命令行界面
和一个名为“mychannel”的 channel

我能够创建 channel “mychannel”并加入来自两个组织的 3 个同行。此外，我能够在两个组织的三个对等节点上安装链码。我正在 Org1 中的 peer0 上实例化链码

在夏天，由于 channel 访问错误，我无法从第二个组织 (Org2) 调用链码。笔记:我正在生成 CA，我已经检查了文件，它似乎是正确的

如果有人能提供帮助，我将不胜感激。
提前致谢

这可能是由错误的 MSPID 名称引起的，例如“orgMSP”是错误的，因为它以小写字母“o”开头使用正确的 MSPID 解决问题

export CORE_PEER_LOCALMSPID="Org1MSP"
