Quickstart failing in GovCloud (OSU)

[awspd]

Updated most of the arn values to reflect OSU and made good progress, however the CF is failling during the LambdaInvokePermission:

The provided principal was invalid. Please check the principal and try again. (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: 4d3b7d0b-4a6e-49e5-8d49-eb00c08ecbb4; Proxy: null)

The following resource(s) failed to create: [InstanceRole, InstallAndConfigureDuoProxyServiceDocument, LambdaInvokePermission]. Rollback requested by user.

Looking for any advice!

Got this working, but it appears the ECS/Fargate clusters do not deploy as part of the quickstart
