block validation policy is not found in the policies of 'Ord

Error message

block validation policy is not found in the policies of 'Orderer' group

What it means

checkConsentersMatchPolicy guard: the Orderer group's Policies map has no 'BlockValidation' entry. The verifier recomputes the expected BlockValidation policy from the consenter mapping and needs to compare it against the configured one; its absence is a malformed orderer config.
