Unable to setup Mutual TLS Auth for AWS API Gateway Custom Domain

Terraform
1

I’m trying to create an AWS API Gateway Custom Domain with Mutual TLS Authentication but it’s giving me an ‘invalid or unknown key’ error.

Code :
resource “aws_api_gateway_domain_name” “api_custom_domain” {

  domain_name               = "${local.api_domain_name}"

  regional_certificate_arn = "${aws_acm_certificate.api_certificate.arn}"

  security_policy = "TLS_1_2"

  endpoint_configuration = {

    types = ["REGIONAL"]

   }

   mutual_tls_authentication = {

     truststore_uri = "s3://${aws_s3_bucket.api_truststore_s3.id}/truststore.pem"

   }

  tags = {

     Name = "${local.api_domain_tags}"

   }

}

Terraform Version : 0.11.10

Error :
“msg”: “Failed to validate Terraform configuration files:\r\n\u001b[31m\n\u001b[1m\u001b[31mError: \u001b[0m\u001b[0m\u001b[1maws_api_gateway_domain_name.api_custom_domain: : invalid or unknown key: mutual_tls_authentication\u001b[0m\n\n\u001b[0m\u001b[0m\u001b[0m\n”

Can anyone please help with this?

This block was added with a recent provider version. Which provider version have you installed?
I’d recommend upgrading your terraform codebase :wink:

“Which provider version have you installed?” : 2.17.0

“I’d recommend upgrading your terraform codebase :wink:” : Sigh ! :disappointed:

Well, we didn’t have too many issues. It isn’t getting better by waiting.
