Generally what means Property "Not currently supported by AWS CloudFormation" for a CDK implementation, specifically:

In the CloudFormation Properties for the Cognito Userpool Lambda Config it says: CustomEmailSender - Not currently supported by AWS CloudFormation. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cognito-userpool-lambdaconfig.html

In the CDK for Cognito.CfnUssrPool this property is described: https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-cognito.CfnUserPool.LambdaConfigProperty.html#customemailsender

My question now is whether this can be implemented with CDK at all? Currently, our Cognito is provided completely via CDK and I would like to keep it that way.

CodePudding user response：

No, it cannot be implemented, as CDK transpiles into CloudFormation. It will work once CloudFormation supports it.
