Connection string to CB database server

Couchbase Server
1

We got a interesting an issue with our setup.
3 data
2 index
2 query and search

Application when connects to all these servers in the connecting string, it gave an error:-
[10.166.70.206:11210][KeyValueEndpoint]: Authentication Failure: Bucket not found on Select Bucket command

So when we removed 2 servers of indexing and 2 for query/ search from connection string of app, issue got resolved.

My question is
Is application connections string only specifies data service?

Thanks

Yes, the connection string uses the data service, so the bootstrap nodes need to have the data service. There’s a future change that should make this distinction go away. Sorry for the confusion!
