Server compatibility?

Hello, I have a Couchbase V2.2.0 production DB.

I am getting an error (Operation not supported], Couldn’t schedule n1ql query) trying to run a simple select statement.

I couldn’t find much on this error and am wondering if my Couchbase DB version is the issue? I can’t seem to find any info on what versions of the API are compatible with what versions of the DB server either.

Thanks for any help!

Querying is available starting from Couchbase Server 4.0

Thanks @mnunberg – that explains it.
