Timelion: Error: Expected: "$" @ character undefined

[BurkovBA]

Describe the feature:
I have apache logs, loaded into Elasticsearch index, called access_log, via Filebeat and Logstash. I'm trying to use Timelion to show a chart with 2 metrics:

• all user requests to my website
• requests to the search API only

For that end I'm writing the following Timelion request:

.es(*), es(index="access_log", metric="sum:request")

However, this fails with this error message:

Timelion: Error: Expected: "$" @ character undefined             More Info OK 166s

Just .es(*) works and draws something:

Kibana version:
5.4.3
Elasticsearch version:
5.4.3
Server OS version:
RedHat 6
Browser version:
Chrome 58.0.3029.110
Browser OS version:
MacOS Sierra 10.12.5
Original install method (e.g. download page, yum, from source, etc.):
From source, run on openJDK 1.8

there is a syntax error in your query, you are missing a dot:

.es(*), .es(index="access_log", metric="sum:request")

@ppisljar Thank you very much, sorry for troubling you because of a basic syntax error.
