Terraform Configuration Files

resource "datadog_dashboard_json" "metrics" {
  dashboard_lists = [12345678]
  dashboard       = <<EOF
{...}
EOF
}

resource "datadog_dashboard_json" "cost" {
  dashboard_lists = [987654]
  dashboard       = <<EOF
{...}
EOF
}

Relevant debug or panic output

N/A

Expected Behavior

Relevant dashboard lists should be updated to include defined dashboard

Actual Behavior

Terraform reports no changes to make and does not edit downstream lists dashboards should have been added to

Steps to Reproduce

1. Define a datadog_dashboard_json resource without any lists to add dashboard to
2. Add a new dashboard list to add dashboard to
3. Run terraform apply
4. Terraform reports no changes even though it currently does not exist in the list we want the dashboard added to
