Start by reproducing the two Microsoft.RecoveryServices/vaults/replicationFabrics/replicationNetworks/replicationNetworkMappings resources using API version 2023-06-01 and inspect the ArmResourceName error. Compare the two mapping definitions and the corresponding Azure resource schema; done means both replication network mappings deploy successfully without the reported BadRequest.
