ec2_vpc_route_table not working with NAT gateways

Having troubles trying to setup the route tables in a VPC with a NAT gateway as the target.

`

  • name: Create Private B route tables
    ec2_vpc_route_table:
    vpc_id: ‘{{ vpc_id }}’
    region: ‘{{ vpc_region }}’
    subnets:
  • ‘{{ vpc_subnet_private_b }}’
    routes:
  • dest: 0.0.0.0/0
    instance_id: ‘nat-0f0e9840ce4984705’
    resource_tags: { “Name”:‘Private B’ }
    register: vpc_private_b_route_table

`

The route table is created, but only has the default local route and not the one I am trying to create to the NAT gateway. Any ideas on what is going on or what I am doing wrong greatly appreciated!
