const app = express();
const port = 8899;

app.set('view engine', 'ejs');
app.use(expressLayout);

// BUILTIN MIDDLEWARE
app.use(express.static('public'));

app.get('/contact', (req, res) => {
    const contacts  = loadContact();
    const dataaxio = loadDataPesan("SUBS","912830123");

    
    console.log(dataaxio); // **HERE MY PROBLEM RESPONSE ALWAYS Promise { }**
    
    res.render('contact', { 
        layout: 'layouts/main-layout',
        title: 'Halaman Contact',
        contact:contacts,
    });
})

thanks you in advance if someone can help me

i try given async in function but it same also i try callback response its same also

>Solution :

Use async/await to wait for the result. You may need to catch the error.

app.get('/contact', async (req, res) => {    <-- convert it to async function
    const contacts  = loadContact();
    const dataaxio = await loadDataPesan("SUBS","912830123");  <-- await for response

    
    console.log(dataaxio); 
    
    res.render('contact', { 
        layout: 'layouts/main-layout',
        title: 'Halaman Contact',
        contact:contacts,
    });
})

and return the data from loadDataPesan function as

loadDataPesan = async function(opts) {
  try {
    const response = await axios.get('localhost/getData', {
      params: {
        opt: opts,
        nis: "123123",
      }
    });

    console.log(response.data.datas); // Log the correct data
    return response.data.datas; // Return the data

  } catch (error) {
    console.error(error);
    throw error; // Throw the error to be caught by the caller
  }
}
