(closed - duplicate) Node-red-contrib-mysql2

i have try to use node-red-contrib-mysql2 node
In nodered documentation it is said

mysql nodes for node-red with paramaterization.

npm install node-red-contrib-mysql2

This is a fork to the original node-red-contrib-mysql, but changed the connection from pool to single connection at a time. We can also send the server details using msg.server, without adding those details at node level.

Can you explain how to format msg.server ?
i try this way but it doesn't works

var test= {Host:mariadb_Host,Port:mariadb_Port, Username: mariadb_Username, Password: mariadb_Password, Database: 'test'}

Olease don't post the same question multiple times. It wastes people's time.

I'm closing this thread
