Annotation Query Failed n.datapoints is undefined (since 6.5.1)

Hello everyone,

I’m a long time Grafana user & recently bumped my installation from 6.4.2 to 6.5.1. Since then a lot of my dashboards display multiple error messages at loading: “Annotation Query Failed: n.datapoints is undefined”. It used to work fine on 6.4.2.

Annotations are loaded from graphite (version 0.9.15).

Any idea how I can investigate this issue? I looked at the XHR requests and what I can see is that the api/annotations endpoint returns an empty array.


I downgraded to 6.4.2 to resolve this annoying issue.
