Steps to Reproduce

1. Terraform apply then prompt error:

2. If comment customer part as below, terraform apply runs normally

   domain_endpoint_options {
     #custom_endpoint_enabled         = true
     #custom_endpoint                 = "logs.${var.region}.${var.testdomain}"
     #custom_endpoint_certificate_arn = data.aws_acm_certificate.test_cert.arn
     enforce_https                   = true
     tls_security_policy             = "Policy-Min-TLS-1-2-2019-07"
   }
