Deploy with pre-provisioned nodes fail

Issue

• We are following this doc to deploy a pre-provisioned host using a separate network so we create the file pre-ctlplane-assignments.yaml with the content:

[...]
parameter_defaults:
  NeutronPublicInterface: eth1
  EC2MetadataIp: 10.254.2.159
  ControlPlaneDefaultRoute: 10.254.2.159
  DeployedServerPortMap:
    control_virtual_ip:
      fixed_ips:
        - ip_address: 10.254.2.159
      subnets:
        - cidr: 24
    controller-0-ctlplane:
      fixed_ips:
        - ip_address: 10.254.2.174
      subnets:
        - cidr: 24
    compute-0-ctlplane:
      fixed_ips:
        - ip_address: 10.254.2.177
      subnets:
        - cidr: 24

But the deploy fails with message:

2020-10-30 21:19:12Z [overcloud]: CREATE_FAILED  'int' object has no attribute 'split'
2020-10-30 21:19:12Z [overcloud]: CREATE_FAILED  'int' object has no attribute 'split'
2020-10-30 21:19:12Z [overcloud]: CREATE_FAILED  'int' object has no attribute 'split'
2020-10-30 21:19:12Z [overcloud]: CREATE_FAILED  'int' object has no attribute 'split'

 Stack overcloud/19565321-c3a4-4ec2-88bf-ae3aa8a758b3 CREATE_FAILED 

Heat Stack create failed.
Heat Stack create failed.

• So we changed the content to:

[...]
parameter_defaults:
  NeutronPublicInterface: eth1
  EC2MetadataIp: 10.254.2.159
  ControlPlaneDefaultRoute: 10.254.2.159
  DeployedServerPortMap:
    control_virtual_ip:
      fixed_ips:
        - ip_address: 10.254.2.159
      subnets:
        - cidr: 10.254.2.0/24
      network:
        tags:
          - 10.254.2.0/24
    controller-0-ctlplane:
      fixed_ips:
        - ip_address: 10.254.2.174
      subnets:
        - cidr: 10.254.2.0/24
      network:
        tags:
          - 10.254.2.0/24
    compute-0-ctlplane:
      fixed_ips:
        - ip_address: 10.254.2.177
      subnets:
        - cidr: 10.254.2.0/24
      network:
        tags:
          - 10.254.2.0/24

• Now we are receiving the message:
