Error while trying to configure ArangoDB replication

While trying to configure an async replication on an ArangoDB database (using the document https://github.com/arangodb/arangodb/blob/dd912dcaec4843f15ce230c477a83ac90052c2bf/Documentation/Books/Manual/Administration/Replication/Asynchronous/Components.md) I got this error:

JavaScript exception in file

Any idea what could have caused it? I'm on the latest 3.3.3 version with a cluster up and running on 3 different machines.

Solution

You are accessing a coordinator. The replication API resides only on DB servers in an ArangoDB cluster. You will see a different behavior if you move to DB servers.
