我正试图从用户处进行交易，但当我试图获取通道时，我收到以下错误：

问题可能来自configtx.yaml，您必须正确放置所有“MSPDir”，并且在发出命令时，必须根据该“MSPDir”设置环境变量。
因此，问题在于为组织创建锚节点的脚本。错误通过bash泄漏。在为两个组织添加锚节点后，问题得到解决，我可以进行事务处理。
有时，如果链码未实例化或未在通道中定义，则会发生这种情况。最好检查Docker容器以了解此错误背后的原因。
如果您正在运行FB测试网络，您可以使用

./monitordocker.sh fabric_test

MSP目录设置正确。如果你仔细观察两次中的一次，你想执行什么事务？您是否已将客户端配置为使用组织的凭据？两个组织都加入频道了吗？智能合约是否实例化？客户端仅配置为使用org2，是的，两个组织都已加入，并且在通道上提交了正确的链码（这两个组织都已批准）。如何为组织添加锚节点？
