ER_ACCESS_DENIED_ERROR when connecting via mysqlrouter

Hi,
I have a node.js project using "mysql2", "^3.6.0" and "typeorm", "^0.3.17". Then I have set up mysqlrouter in the same server as recommnded. mysql innodb cluster is set up with 3 nodes.
There is no problem connecting to the cluster when connecting directly to any of the cluster nodes from the node.js project. However when I set the connection to go through mysql router, ER_ACCESS_DENIED_ERROR is thrown.
Even as it fails, I am able to connect via mysqlrouter via mysql console or mysql-shell.
Below is the output of the error:

/home/devops/cd-api/node_modules/mysql2/lib/packets/packet.js:728
    const err = new Error(message);
                ^

}

Start by reproducing the reported mysql2 connection through MySQL Router and compare it with a direct cluster connection and the working mysql console or mysql-shell connection. Inspect the mysql2 ClientHandshake and packet error paths named in the stack trace, then document or demonstrate the cause of the access denial and the conditions for a successful connection.
