Estoy tratando de actualizar varias columnas de una tabla siguiendo un mensaje de consulta. Recibo un error después de la instrucción db.query. Aquí está mi código:

 function updateEmpRole() { db.query( 'SELECT * FROM role', function(err, results) { const role = results.map(role => { return {name: role.title, value: role.id} }); if (err) throw err; db.query( 'SELECT * FROM employee', function(err, results) { const employee = results.map(employee => { return {name: employee.first_name+' '+employee.last_name, value: employee.id} }); if (err) throw err; db.query( 'SELECT * FROM employee WHERE manager_id IS NULL', function(err, results) { const manager = results.map(manager => { return {name: manager.first_name+' '+manager.last_name, value: manager.id} }); if (err) throw err; inquirer.prompt([ { type: 'list', name: 'id', message: 'Select an employee to update:', choices: employee }, { type: 'list', name: 'role_id', message: 'Please assign a new role:', choices: role }, { type: 'list', name: 'manager_id', message: 'Please assign a manager:', choices: manager } ]) .then((response) => { db.query( `UPDATE employee SET role_id = ?, manager_id = ? WHERE id = ?`, response, function(err, results) { console.table('Employee successfully updated.'); if (err) throw err; startApp(); }) }) })})})};

¿Cómo debo especificar correctamente SET? Solo quiero actualizar role_id y manager_id.
