Hyperledger Fabric 交易背书报错 no peer combination can satisfy the endorsement policy
例子：https://github.com/hyperledger/fabric-samples/tree/main/asset-transfer-events https://github.com/hyperledger/fabric-samples/tree/main/asset-transfer-basic
<dependency>
<groupId>org.hyperledger.fabric</groupId>
<artifactId>fabric-gateway</artifactId>
<version>1.0.1</version>
</dependency>
用 fabric-gateway 调用合约的时候会在背书的时候出现错误：io.grpc.StatusRuntimeException: FAILED_PRECONDITION: no combination of peers can be derived which satisfy the endorsement policy: no peer combination can satisfy the endorsement policy。
因为背书的时候只将背书请求发送给了一个节点。
提了一个 issues: https://github.com/hyperledger/fabric-gateway/issues/400
问题原因: 因为没有更新通道中组织的锚节点，没有选定锚节点的时候节点之间无法进行 gossip 通信，使用服务发现的时候只能发现当前指定 server 的单个节点。更新了组织的锚节点配置后就可以发现全部的节点了。
