I try to authenticate end-users of my application at ELB level by using Cognito provided feature.
I first deployed all my resources in eu-west-1 and works perfectly.
When trying to do the same in eu-west-1, CloudFormation sent me an error:
Resource handler returned message: "Invalid request provided: AWS::ElasticLoadBalancingV2::ListenerRule Validation exception"
Also see a trace in Cloud Trail (partial copy)
"eventTime": "2022-04-11T13:47:08Z",
"eventSource": "elasticloadbalancing.amazonaws.com",
"eventName": "CreateRule",
"awsRegion": "eu-west-3",
"sourceIPAddress": "cloudformation.amazonaws.com",
"userAgent": "cloudformation.amazonaws.com",
"errorCode": "ValidationException",
"errorMessage": "Action type 'authenticate-cognito' must be one of 'redirect,fixed-response,forward,authenticate-oidc'"
I suspect that this feature is not yet available in eu-west-3, but can't find an official answer (which region supports this feature).
Thanks for your help
