问题 I'm trying to start an Hyperledger Fabric network in v1.2 with a network generated by myself (with binary configtxgen ). The network starts correctly and no component indicates an error. However, when I try to create a new channel, an error occurs at the orderer level (one of the following three errors) and no channel is created. Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group]
