[Bug]: Message: "$.network-function-groups: null found, array expected" even when there is a network function group defined

[sameesin]

Terraform Core Version

1.9.1

AWS Provider Version

5.57.0

Affected Resource(s)

data source - "aws_networkmanager_core_network_policy_document"

data "aws_networkmanager_core_network_policy_document" "policy1" {
  core_network_configuration {
    asn_ranges = ["65022-65534"]

    edge_locations {
      location = "ap-south-1"
    }

Expected Behavior

The core network should get created but the code fails with an error stating incorrect policy

Actual Behavior

{
│ RespMetadata: {
│ StatusCode: 400,

I'm able to reproduce this using the configuration files provided by @sameesin. It looks like using the create_base_policy argument with no other arguments causes the provider to generate an invalid base policy.

Note this is also causing multiple acceptance test failures:

Possible workarounds

1. Use the base_policy_document argument in the aws_networkmanager_core_network resource to force the use of a working policy:

resource "aws_networkmanager_core_network" "core_network" {
  global_network_id = aws_networkmanager_global_network.cloudwan-automation-test.id
  create_base_policy = true
  base_policy_document = data.aws_networkmanager_core_network_policy_document.policy1.json
}

2. Use the AWSCC provider and the corresponding resource type to create and manage the core network:

resource "awscc_networkmanager_core_network" "example" {
  global_network_id = aws_networkmanager_global_network.cloudwan-automation-test.id
  description       = "example"
}
