Invalid IAM Instance Profile name

Terraform Providers AWS
1

Hi,

I am new here, sorry if this topic is already created.

I am trying to create role, policy, ec2 instance profile from terraform(2 .json files includes access to ec2), below is the .tf file, please advise where am I doing wrong.

iamroles.tf

resource "aws_iam_role_policy" "ec2_policy" {
  name        = "ec2_policy"
  role        = "aws_iam_role.javahome_ec2_role.id"
  policy      = file("ec2-policy.json")
}
resource "aws_iam_role" "javahome_ec2_role" {
  name               = "javahome_ec2_role"
  assume_role_policy = file("ec2-assume-policy.json")
}
resource "aws_iam_instance_profile" "ec2_profile" {
  name  = "javahome_ec2_profile"
  role = "aws_iam_role.javahome_ec2_role.name"
}

ec2-machines.tf

provider "aws" {
  region = var.region
  }  
resource "aws_instance" "web" {
  ami             = var.ami[var.region]
  instance_type   = "t2.micro"
  iam_instance_profile = "aws_iam_instance_profile.ec2_profile.name"
  tags = {
    Name = "HelloWorld"
  }
}

variables.tf

variable "region" {
  default = "us-west-2"
}
variable "ami" {
  type = map
  default = {
    us-west-2 = "ami-0b1e2eeb33ce3d66f" # US West (Oregon)
  }
  description = "have only added one region"
}

Receiving the below 3 error messages while running terraform apply -
