Has anyone here managed to associate an Elastic IP address with an AWS Network Load Balancer?

I’m having problems with the AWS module elb\_network\_lb.

I’m trying to associate Elastic IPs with the subnets I’m attaching the load balancer to, and I keep getting the same message:

An error occurred (ValidationError) when calling the CreateLoadBalancer operation: At least one subnet must be specified"

If I use the subnet\_ids attribute, I get a load balancer across two subnets, but without Elastic IP addresses. But if I use the subnet\_mappings attribute, which is the only way to associate an Elastic IP address with a subnet, I get the above error message.

Uncle Google has been of little help…
