Can we see your code? You're passing properties eventSelectors and includeManagementEvents to the Trail constructor, but it doesn't take either of those properties...

Ah never mind, I had the wrong collapsible open on the doc page. No, that example is wrong, since you must provide the s3BucketName.

I see the problem.. the Terraform docs (from which the Pulumi docs are generated) look like this:

resource "aws_cloudtrail" "example" {
  # ... other configuration ...

  event_selector {
    read_write_type           = "All"
    include_management_events = true

    data_resource {
      type   = "AWS::S3::Object"
      values = ["arn:aws:s3:::"]
    }
  }
}

The "... other configuration ..." bit includes s3BucketName.

That'll be a tricky one to fix.. I guess they'll have to update the generated code, which is always fraught...

I'll raise a ticket.
