Hi, need some help please. I was required to use cloudformation stack to create s3 buckets in 3 regions using cloudformation.NewStack, then i need to replicate them mutually using s3.NewBucketReplicationConfig. Inside template yaml file, specify the BucketName and ARN as the Outputs, but i have the problem to get the Outputs from cloudformation stack since the Outputs are empty. I’m new to pulumi, so I am wondering whether there is a functionality to wait for the cloudformation stack creations, or any post hook to run replication process? Appreciate it if someone can provide some ideas.
