Terraform dynamic block inside a nested block not passing in values

I am looking to use the google_os_config_guest_policies resource and am having issues with being able to pass in values to the nested block of code for package_repositories.

https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/os_config_guest_policies

Child module main.tf

package_repositories {
      dynamic "apt" {
        for_each = var.apt
        content {
          archive_type = lookup(apt.value, "archive_type", "abc")
          uri          = lookup(apt.value, "uri", "abc")
          distribution = lookup(apt.value, "distribution", null)
          components   = lookup(apt.value, "components", null)
          gpg_key      = lookup(apt.value, "gpg_key", null)
        }
      }
  }

Variables.tf

variable "apt" {
  description = "Variable used for the APT block supported in the package_repositories variable. Pass in variables for apt_archive_type, apt_components, apt_distribution, apt_uri, apt_gpg_key."
  type        = any
  default     = []
}

terraform.tfvars

apt = [
  {
    archive_type = "DEB"
    uri          = "https://packages.cloud.google.com/apt"
    distribution = "cloud-sdk-stretch"
    components       = ["main"]
  }
]

Whenever I try to pass in values from my tfvars I only get a blank package_repositories map passed in during my terraform plan step.

+ package_repositories { }

I have tried to remove the dynamic block and statically define the values forpackage_repositories which worked without any issues.

package_repositories {
    apt {
      archive_type = "DEB"
      uri          = "https://packages.cloud.google.com/apt"
      distribution = "cloud-sdk-stretch"
      components       = ["main"]
  }
}

If I try to rework my code to use the dynamic apt block it would try to pass in null values. Is there something wrong with syntax or is this due to being a beta resource where the dynamic block isn't working?

I tried running it, I got the desired output

     + package_repositories {
          + apt {
              + archive_type = "DEB"
              + components   = [
                  + "main",
                ]
              + distribution = "cloud-sdk-stretch"
              + uri          = "https://packages.cloud.google.com/apt"
            }
        }

Can u please confirm are you using terraform.tfvars or any other tfvars file. If other file , are u passing to your terraform plan using -var-file ?
