Amazon web services – Terraform aws_eip resource getting "Error" of Value for unconfigurable attribute

I am new to Terraform and following a tutorial on how to create aws_elasticip module. When i perform ‘terraform plan’ this issue is present and i can’t move forward with creating my terraform file.

 terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.16"
    }
  }
}

provider "aws" {
  region = "eu-west-2"
}

resource "aws_eip" "lb" {
  domain = "vpc"
}

I have also attempted to do this with a instance variable declared and the error still persists

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.16"
    }
  }
}

provider "aws" {
  region = "eu-west-2"
}

resource "aws_vpc" "vpc_a" {
  cidr_block = "10.0.0.0/16"
}

resource "aws_instance" "server_a" {
    ami = "ami-06464c878dbe46da4"
    instance_type = "t2.micro"
}

resource "aws_eip" "lb" {
    instance = aws_instance.server_a.id
    domain = "vpc"
}

The error I am getting is below.
