Same with empty excludeOwner

excludeOwner:
  user:

butler[603084]: /snapshot/butler/src/lib/smtp.js:416
butler[603084]:             const matchExcludedUsers = excludeUsers.filter(
butler[603084]:                                                     ^

Long overdue, a fix for this is coming in next version of Butler.
Thx for reporting the issue btw!

The workaround would be to disable (in the YAML config file) the features causing problems, but it's of course better that Butler itself is resilient and deals with empty recipient lists in a good way.
