Need clarification on:
Available methods to connect to Neo4j Causal Cluster from a Node.js application.
The connection string that we need to use to connect to the Neo4j Causal Cluster consists of 3 Core Servers for Write/Read operation from a Node.js application.
Got the below error from the Node.js application when using bolt+routing://<MULTIVALUE_DNS_RECORD> connection string.

Version details
Neo4j Enterprise Version: 4.3.6
Node JS : 14.3
neo4j-driver : 4.4.1
It would be a great help if any one can give a solution on this.

See the "available URI schemes" table in this documentation. Client applications - Neo4j Java Driver Manual
I think you should change your URI schemee and use neo4j+s or neo4j+ssc instead of bolt+routing. You are using a driver that is > 4.4, and neo4j:// schemes replace bolt+routing and do the same thing.
