Why am I getting a Invalid template body error when building this terraform template for aws service catalog?

Here is the terraform template for aws service catalog that I am building.

resource "aws_servicecatalog_product" "data-ml-pipeline-service-catalog-product" {
  name  = "data-ml-pipeline-service-catalog-product"
  owner = "data-ml"
  type  = "CLOUD_FORMATION_TEMPLATE"

  provisioning_artifact_parameters {
    template_url = "https://s3.amazonaws.com/cf-templates-ozkq9d3hgiq2-us-east-1/temp1.json"
    type  = "CLOUD_FORMATION_TEMPLATE"
  }

Based on this question, Terraform /AWS aws_servicecatalog_portfolio, this should work.

Exact error: Error: error creating Service Catalog Product: InvalidParametersException: Invalid templateBody. Please make sure that your template is valid

Edit: Here is the new template that I am using.

I'd like to provide a general answer to this error message.
AFAIK, InvalidParametersException: Invalid templateBody. Please make sure that your template is valid can imply that AWS cannot access the template you're trying to create a Service Catalog product version from (the one which is usually provided by key LoadTemplateFromURL). There are 2 possible reasons for this:

• The URL of the template to deploy is invalid. Make sure that the URL provided actually points to a template file. When using Cloudformation with variables inside the URL, make sure to use !Sub etc.
• The IAM user/role executing the deployment may not have the required permissions, as seen in a different SO question. Make sure that the permission cloudFormation:validateTemplate is in place.

Basically, this error message is misleading because it suggests that the template is invalid but actually the template cannot even be accessed in the 1st place.
