Prepare statements not able to decode OrderedIntersectScan

Looks like https://github.com/couchbase/query/blob/master/plan/op_registry.go
has missing OrderedIntersectScan plan operator

The strange thing is sometimes the query returns result, sometimes it gives me this error.
The query is formed like this:

SELECT autocompleteInfo.* FROM products
WHERE 1 = 1 AND type <> 'shop'
AND stats.rankingPosition is not missing
AND ANY v IN searchKeyA SATISFIES v = $1 END
[AND ANY v IN searchKeyA SATISFIES v = $2 END ...]
ORDER BY stats.rankingPosition
LIMIT 7;
