no values in 'Orderer' group

Error message

no values in 'Orderer' group

What it means

checkConsentersMatchPolicy guard: the Orderer group in the proposed config exists but its Values map is empty, so the 'Orderers' (consenter mapping) value cannot be read. The smartbft config verifier cannot reconstruct the expected block-validation policy from an empty group.

Solutions

1. Fix the config update so the Orderer group retains its Orderers value
2. Regenerate the config update from a complete current config
