Error Error launching instance possible mismatch of Security Group IDs and Names See AWS Instance docs here https terraform io docs providers aws r instance html

Question

Hi Guys,

I am trying to launch an EC2 instance using terraform, but it is showing me the below error.

Error: Error launching instance, possible mismatch of Security Group IDs and Names. See AWS Instance docs here: https://terraform.io/docs/providers/aws/r/instance.html.
        AWS Error: InvalidParameterValue: Value () for parameter groupId is invalid. The value cannot be empty
        status code: 400, request id: de662e5a-4b53-4f83-a1dd-ab476b88061b
  on ec2.tf line 6, in resource "aws_instance" "myin2":
   6: resource "aws_instance" "myin2" {

How can I solve this error?

Hi@akhtar,

According to your error, you didn't specify your security group properly. AWS is not able to match your security group with their database. So check your security group and use it in your terraform code properly.
