Do a test connection from nodejs to oracle database

Question

I have to test oracle DB from my nodejs application but does not show up any result following is what I have tried

Have also attached screenshot of application frontend from whjere the testconnection is done

const oracledb = require('oracledb'); 
$(document).on('click', '#sourceOracle #testcon', function(event) {
          runTest();
        })
            async function runTest() {
              let conn;
            
              try {
                conn = await oracledb.getConnection({ user: 'OT', password: 'mypassword', connectString: 'localhost:1521/orcl' });
                console.log(conn)
                const result = await conn.execute(
                  'select current_timestamp from dual'
                );
            
                console.log(result);
              } catch (err) {
                console.error(err);
              } finally {
                if (conn) {
                  try {
                    await conn.close();
                  } catch (err) {
                    console.error(err);
                  }
                }
              }
            }

I get below error
