Go (also known as Golang) is an open source programming language developed by Google Couchbase is a NoSQL database built for business-critical applications.

Query (query, &gocb.QueryOptions{NamedParameters: params})  this error didn't occurred.  Running Just  Cluster. Query (query, &gocb.QueryOptions{NamedParameters: params})  after connection directly would get  "failed to get query provider: not connected to cluster | {"statement":"*"}" What I did to  tackle this is, prior to the Query function or immediately after running the connect function I ran a atomic function  collection.
