Using Terraform to create a systems manager document

Hello.

Since "document_format" is set to YAML, I think an error will occur if "mainSteps" is not written in YAML.

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ssm_document

resource "aws_ssm_association" "testa" { name = aws_ssm_document.test.name schedule_expression = "cron(0 0 0 ? * * *)" targets { key = "tag:run_ssm_document" values = ["yes"] } }

resource "aws_ssm_document" "test" {
    name = "test"
    document_format = "YAML"
    document_type = "Automation"

    content =<<DOC

             print("hello world")
