I'm trying to test my logstash configurations that use the aggregate plugin. I have not had any issues running them locally against the binary as I write them. But now I want to test the behavior expectations of the aggregations. Then I found a blog post and docker container that utilize rspec to test the filters. However I was trying to write a test to check the value of eventId and this ConfigurationError pops up. I'm surprised because it seems to me I'm only defining the timeout option in one aggregate block. But perhaps I'm doing something terribly wrong.

LogStash::ConfigurationError:
Aggregate plugin: For task_id pattern '%{eventId}', there are more than one filter which defines timeout options. All timeout options have to be defined in only one aggregate filter per task_id pattern. Timeout options are : timeout, inactivity_timeout, timeout_code, push_map_as_event_on_timeout, push_previous_map_as_event, timeout_timestamp_field, timeout_task_id_field, timeout_tags
