terraform-provider-mongodbatlas: `error deleting MongoDB Network Peering Container`, even though Container exists

Terraform CLI and Terraform MongoDB Atlas Provider Version

Terraform v1.0.8
on darwin_amd64

Your version of Terraform is out of date! The latest version
is 1.0.11. You can update by downloading from https://www.terraform.io/downloads.html

Provider version 1.0.2

Steps to Reproduce

1. Create network container in an existing project, with no clusters in it
2. Create cluster
3. Delete cluster
4. Delete network container -> fails

Debug Output

Ok, so I’ve been coping with this issue for a while and I thought I had fixed it by setting a simple timer between resources, but it resurfaced again even then. It seems strange because, when trying to destroy the network container, the provider is complaining that the network container doesn’t exist, even though it does:

However, I went to the MongoDB Atlas Administration API, and the network container did in fact exist:

{
  "links": [
    {
      "href": "https://cloud.mongodb.com/api/atlas/v1.0/groups/REDACTED/containers/all?pageNum=1&itemsPerPage=100",
      "rel": "self"
    }
  ],
  "results": [
    {
      "atlasCidrBlock": "10.1.128.0/24",
      "id": "61700380003d3701c115dc58",
      "providerName": "AWS",
      "provisioned": true,
      "regionName": "EU_WEST_3",
      "vpcId": "REDACTED"
    }
  ],
  "totalCount": 1
}

You can check it’s the same container ID. I tried deleting it once again with TF, to no sucess (same error).

Then I tried deleting it from the API (to which I got no problems, 200 OK), and upon checking the containers list again:

{
  "links": [
    {
      "href": "https://cloud.mongodb.com/api/atlas/v1.0/groups/REDACTED/containers/all?pageNum=1&itemsPerPage=100",
      "rel": "self"
    }
  ],
  "results": [],
  "totalCount": 0
}

it was successfully deleted.

Worth noting that I’m using the same MongoDB Atlas credentials (and same organization & project ID) throughout my code. So it is not possible that the provider might be picking different project or group ID…

Additional Context

The network container that was trying to delete:

# module.mongodb_atlas_aws[0].mongodbatlas_network_container.default will be destroyed
  - resource "mongodbatlas_network_container" "default" {
      - atlas_cidr_block = "10.1.128.0/24" -> null
      - container_id     = "61700380003d3701c115dc58" -> null
      - id               = "REDACTED" -> null
      - project_id       = "REDACTED" -> null
      - provider_name    = "AWS" -> null
      - provisioned      = true -> null
      - region_name      = "EU_WEST_3" -> null
      - regions          = [] -> null
      - vpc_id           = "REDACTED" -> null
    }

My setup is quite convoluted so unfortunately I’ve not managed yet to provide a minimized reproducer. However, it might be worth investigating why this happens…? Given that (I reckon) it should be a simple DELETE HTTP method.
