This setting must be either True or False.

Depending on your indices, and how you’ve filtered them, an empty list may be presented to the action. This results in an error condition.

When the ignore_empty_list option is set to True, the action will exit with an INFO level log message indicating such. If ignore_empty_list is set to False, an ERROR level message will be logged, and Curator will exit with code 1.

The default value of this setting is False
