Unable return Public IP address ID to bind on an interface

Terraform Providers Azure

I’m trying to create 8 interfaces, first 3 interface need public ip. I have public ip module where I create 3 public ips, and bind these when creating the interfaces. But I get errors like the ones below. Not sure why “ Inappropriate value for attribute “public_ip_address_id”: string required.” Error. Really appreciate if anyone can help. Thanks.
