Invalid index when deploying TGW hub-connector

[k0ff33]

I'm setting up a Transit Gateway in an alternate region with peering connection following this doc and using latest aws-tgw-hub-connector module.

When running atmos terraform apply tgw/hub-connector --stack core-euw1-network I'm getting the following error:

│ Error: Invalid index
│
│   on main.tf line 7, in locals:
│    7:   primary_tgw_hub_account_id = local.enabled ? module.account_map.outputs.full_account_map[local.primary_tgw_hub_account] : null
│     ├────────────────
│     │ local.primary_tgw_hub_account is "core-use1-network"
│     │ module.account_map.outputs.full_account_map is map of string with 20 elements
│
│ The given key does not identify an element in this collection value.

It seems that the primary_tgw_hub[0].output).stack is returned in tenant-environment-stage format instead of tenant-stage.

Do you have an idea how this should be set up?

Here's how the simplified stack looks like:

import:
  - orgs/ark/core/network/_defaults
  - mixins/region/eu-west-1
  - catalog/vpc/defaults
  - catalog/vpc-flow-logs-bucket/defaults
  - catalog/ec2-client-vpn/defaults
  - catalog/tgw/hub/defaults
  - catalog/tgw/attachment/eu-west-1
  - catalog/tgw/routes/defaults
  - catalog/tgw/hub-connector/defaults
  - catalog/vpc-routes/defaults

components:
  terraform:
    vpc:
      ...

    tgw/hub:
      vars:
        enabled: true
        name: tgw-hub
        # Empty connections - we use attachment/routes pattern
        connections: []

    tgw/attachment:
      vars:
        # Route table associations are required in the same account where TGW is deployed
        create_transit_gateway_route_table_association: true

    tgw/hub-connector:
      metadata:
        component: tgw/hub-connector
      vars:
        enabled: true
        primary_tgw_hub_region: us-east-1

    tgw/routes:
      ...

    vpc/routes/private:
      ...

Confirmed this is the same regression tracked in #35. The component now uses tenant-environment-stage for the account key, but account_map.full_account_map is keyed by tenant-stage.

We’ll create a quick PR to fix that and normalize the key before indexing

We have a PR up now! @k0ff33 could you please try this branch? cloudposse-terraform-components/aws-tgw-hub-connector#50

I tested it and works fine!
