RSA public key is not available client side. Either set option `cachingRsaPublicKey` to indicate public key path, or allow public key retrieval with option `allowPublicKeyRetrieval

mariadb.createConnection({

    host: 'localhost',

    user: 'root',

    password: 'pwd',

    database: 'dbname',

    port: 3306,

    connectionLimit: 5,

    allowPublicKeyRetrieval: true

})

 

 

mysql 8.0부터는 allowPublicKeyRetrieval를 true로 해줘야 하는듯하다.
