I used ruby 2.0.0 and 2.3.0 - the same... Which version of ruby I should use? Thanks.

@dmitrych61 The error you're running into seems to only be possible when InfluxDB does not have any retention policies defined. I'm not sure how this is possible since InfluxDB should define the "default" retention policy by default. What version of InfluxDB are you using?

Reassigned to @yorickpeterse

I have this version:

> show diagnostics
name: build
-----------
Branch	Build Time	Commit						Version
master			37992377a55fbc138b2c01edd4deffed64b53989	1.0.0

And there is a policy:

> use gitlab
Using database gitlab
> show retention policies on gitlab
name	duration	shardGroupDuration	replicaN	default
autogen	0		168h0m0s		1		true

I am having the same issue using the same versions as @dmitrych61 to include using the same default retention policy.

Argh bloody hell, it seems InfluxDB decided to change the default retention policy name from "default" to "autogen" in https://github.com/influxdata/influxdb/commit/e3328117a9a2431ebc1252a470573378271fc09d. While supporting this in the Rakefile is feasible doing so in the query files is more complicated. I'll see what I can do.

Status changed to closed by commit 7b68bf80

@jethompson81 @dmitrych61 Commit 7b68bf80 should solve this problem, please give it a try and let me know if it works (or not).

It works like a charm!
Thanks for you.

Perfect! Thank you sir!
