Terraform Version

Terraform Configuration Files

terraform {
  backend "s3" {
    region = "eu-central-1"
    bucket = "*****"
    key    = "terraform-state/***/***/terraform.tfstate"

    encrypt = true
    kms_key_id = "arn:aws:kms:eu-central-1:*********:alias/k*******"
    dynamodb_table = "****"
    assume_role = {
      role_arn = "arn:aws:iam::****:role/*****"
    }
  }
}

Debug Output

Error: Invalid KMS Key ARN

│ on backend.tf line 14, in terraform:
│ 14: kms_key_id = "arn:aws:kms:eu-central-1::alias/"
│
│ Value must be a valid KMS Key ARN, got "arn:aws:kms:eu-central-1::alias/"
