Describe the bug

I just setup a new management account with Control Tower configured.

When installing ADF v.4.0.0 in this account with the following flags using a Cloud9 environment

{"CrossAccountAccessRoleName": "AWSControlTowerExecution", "MainNotificationEndpoint": "", "DeploymentAccountName": "", "DeploymentAccountEmailAddress": "", "DeploymentAccountAlias": "", "DeploymentAccountId": "ID-OF-DEPLOY-ACC", "DeploymentAccountMainRegion": "eu-west-1", "DeploymentAccountTargetRegions": "us-east-1", "ProtectedOUs": "", "LogLevel": "INFO", "AllowBootstrappingOfManagementAccount": "No", "GrantOrgWidePrivilegedBootstrapAccessUntil": "1900-12-31T23:59:59Z"}

the installation successfully completes but the aws-deployment-framework-bootstrap-pipeline fails with

I assume it's attempting to send a notification but is unable to do so as I set "MainNotificationEndpoint": ""
I would like some help in figuring out if the notification error is the "real" error or if this error is just hiding some other underlying issue.

Expected Behavior

If I set "MainNotificationEndpoint": "" it won't try to run the notification part of the code

Current Behavior

Setting "MainNotificationEndpoint": "" results in an error

Steps To Reproduce

1. Install ADF v4 with these flags

{"CrossAccountAccessRoleName": "AWSControlTowerExecution", "MainNotificationEndpoint": "", "DeploymentAccountName": "", "DeploymentAccountEmailAddress": "", "DeploymentAccountAlias": "", "DeploymentAccountId": "ID-OF-DEPLOY-ACC", "DeploymentAccountMainRegion": "eu-west-1", "DeploymentAccountTargetRegions": "us-east-1", "ProtectedOUs": "", "LogLevel": "INFO", "AllowBootstrappingOfManagementAccount": "No", "GrantOrgWidePrivilegedBootstrapAccessUntil": "1900-12-31T23:59:59Z"}

2. The aws-deployment-framework-bootstrap-pipeline pipeline step UploadAndUpdateBaseStacks will fail

Possible Solution

Workaround is to modify the adfconfig.yml in codecommit and add a notification endpoint. Once added the pipeline will succeed.

Additional Information/Context

No response

ADF Version

v4.0.0

Hi @KarBroden,

This seems to be a bug in the validation logic. It should not allow you to install ADF without it.
When you install ADF, you are required to specify the MainNotificationEndpoint as written in the parameters description.
Not setting the notification endpoint is unsupported, so this may cause issues elsewhere.

Therefore I would recommend that you update the adfconfig.yml and include this configuration:

# ...
config:
  main-notification-endpoint:
    - type: email
      target: [email protected]

Best regards, Simon

Thanks for looking into this. The installation guide mentions this configuration parameter as optional. If it's not we should change the documentation as well.
