Issue in returning promise in node.js

Question

I am currently using ssh2-sftp-client library to connect with sftp but I am using keyboard-interactive on method to resolve one issue I need to return the resolve after a both connect and on method are resolved. Below is my code

    const Client = require('ssh2-sftp-client');
    const sftp = new Client();

    const connectToSFTP = config => {
      console.log(config);
      return new Promise((resolve, reject) => {
        sftp.connect({
          host: config.host,
          port,
          username: config.username,
          tryKeyboard: true
        }).then(data => {
          console.log(data);
          resolve(data);
        }).catch(err => {
          console.log(err);
          reject(err);
        });

        sftp.on('keyboard-interactive', (name, instructions, instructionsLang, prompts, finish) => {
          console.log('Connection :: keyboard-interactive');
          finish([config.password]);
        })
      });

    };

const functionOne = () => {
     return new Promise((resolve, reject) => {
            resolve('somedata');
     })
}

const functionTwo = () => {
return Promise.all(lodash.map(data, (item, item1) => {

          return connectToSFTP(item.config)
              .then(data => {
                console.log(data); //cannot see data

              }).catch(err =>{
                 console.log(err);
               })  
       })

}

functionOne()
  .then(data => {
    return functionOne();
  })
  .then(data => {
    return functionOne();
  })
  .then(data => {
    return functionOne();
  })
  .then(data => {
    console.log('second');
    return functionTwo();
  }).then(data => {
  console.log('finished');
})
  .catch(err => {
    console.log(err);

  });

After everything is finished then return resolve, how can I achieve this?

You need to call `connect` function to see this. It will not call itself magically — ponury-kostek, Dec 14 '18 at 15:24
from your code it is not obvious which function is returning (return Promise.all), can you please put the whole code — Muho, Dec 14 '18 at 15:25
@Mohammadaltenji I have updated the code can you please see it — JN_newbie, Dec 14 '18 at 16:47
Avoid the [`Promise` constructor antipattern](https://stackoverflow.com/q/23803743/1048572?What-is-the-promise-construction-antipattern-and-how-to-avoid-it)! — Bergi, Dec 14 '18 at 17:40
If you put console.log before return connectToSFTP you see something? — ponury-kostek, Dec 14 '18 at 17:43
