error retrieving consenter of type: %s

Error message

error retrieving consenter of type: %s

What it means

newChainSupport guard: the consensus type from the channel's shared config has no consenter registered in the consenters map passed to the registrar. The channel config names a consensus plugin (e.g. etcdraft, smartbft) that this orderer binary does not have registered.

Solutions

1. Run an orderer binary that includes the requested consensus type
2. Change the channel's consensus type to one supported by this orderer
