To piggy back on this, it doesn't work in the webui either.

I just saw this in the release notes of 3.0.0beta

Note
This is a beta pre-release with ElasticSearch 7 support. As such there will be bugs, testing rules for example is currently broken in ElastAlert v0.2.0b2 (Yelp/elastalert#2204 (comment)).
