Terraform | 0.12.2 | Upgrade issues

Question

I am getting below error while executing terraform init command after upgrading to 0.12.2 version. Earlier same code was working fine without issues in terraform 0.11.10 version.

alb.tf

tags {
    Name             = "${var.name}"
    Environment      = "${lookup(var.environment, terraform.workspace)}"
  }

lc.tf:-

  vars {
EFS_ENDPOINT = "${aws_efs_file_system.jenkins.dns_name}"

}

remote_state.tf line 4

config {
    bucket      =   "s3-terraform-state"
    key         =   "env:/${lookup(var.environment, terraform.workspace)}/cicd-security-groups/terraform.tfstate"
    region      =   "${var.region}"
  }

remote_state.tf line 14

config {
    bucket      =   "ttgsl-s3-terraform-state"
    key         =   "env:/${lookup(var.environment, terraform.workspace)}/cicd-kms-ebs/terraform.tfstate"
    region      =   "${var.region}"
  }

terraform validate -no-color

Blocks of type "tags" are not expected here. Did you mean to define argument
"tags"? If so, use the equals sign to assign it a value.

Answer 1

tags = {
    Name             = "${var.name}"
    Environment      = "${lookup(var.environment, terraform.workspace)}"
  }

vars = {
    EFS_ENDPOINT = "${aws_efs_file_system.jenkins.dns_name}"
}

We need to add = after tags, vars as well for config to avoid the errors.
