I want to deploy an ec2 instance on aws.

This is my resource code

data "aws_ami_ids" "ubuntu" {
  owners = ["099720109477"] 

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-*"]
  }
    
  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }
  
}

output "test" {
  value = data.aws_ami_ids.ubuntu
}

resource "aws_instance" "myec2" {
  ami             = "${data.aws_ami_ids.ubuntu.id}"
  instance_type   = var.instancetype
  key_name        = "devops-era"`
  security_groups = ["${aws_security_group.allow_http_https.name}"]

  tags = {
    Name =  "var.aws_common_tag" 
  }  
}

But I keep getting the below error whenever I run terraform apply:

Error: creating EC2 Instance: InvalidAMIID.Malformed: Invalid id: "203304658" (expecting "ami-...")
│   status code: 400, request id: 35b803fd-a6c8-4632-82ee-2936c9cbf062
│ 
│   with aws_instance.myec2,
│   on mini-projet.tf line 28, in resource "aws_instance" "myec2":
│   28: resource "aws_instance" "myec2" {

I don't understand why

Any suggestions here will be appreciated

Your data source query returns multipe AMI ids. You have to choose explicitly which one you want, e.g. to use the first one:

ami           = data.aws_ami_ids.ubuntu.ids[0]
