Puppet manifest has a file declaration that somehow duplicates itself

Question

Given the confusing error message:

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Duplicate declaration: File[/etc/logstas

Answer 1

This probably means that you're including the file twice. Do you include the logstash module twice anywhere? It's possible that you're meaning to include it twice, but with different config dirs. If you're accidentally including it twice with the same config dir, then you'll get the error.
