Node js promise-ftp: Error uploading file: Error: Can't open that file: No such file or directory

Question

Using node js server and promise-ftp library, i want to upload a file "inventory.txt" to the FTP Server.

These are the imports:

const fs = require("fs");
const path = require("path");
const PromiseFtp = require("promise-ftp");
const ftp = new PromiseFtp();

This is the code:

      const filePath = path.join(__dirname, "./inventory.txt");

      // send file to FTP server
      const { host, userName, pwd, destPath } = sails.config.ftpkey;
     
      // check if file exists
      if (!fs.existsSync(filePath)) return res.status(500).send("File not found. Please try again.");
      else console.log("File exists");

      ftp
        .connect({
          host: host,
          user: userName,
          password: pwd,
        })
        .then(function (serverMessage) {
          console.log("Server message: " + serverMessage);
          return ftp.put("./inventory.txt", destPath);
        })
        .then(function (serverMessage) {
          console.log("File uploaded successfully");
          return ftp.end(); // Close the FTP connection
        })
        .then(function () {
          res.send("File uploaded");
        })
        .catch(function (err) {
          console.error("Error uploading file:", err);
          res.status(500).send("Error uploading file");
        })
        .finally(() => {
          ftp.end();
        });

This is the consoled response:

}

The FTP configurations are correct to my knowledge but i am not able to upload my file

Note: Since the inventory.txt file in in the same folder, i have tried both ftp.put(filePath, destPath); & ftp.put("./inventory.txt", destPath);

Answer 1

The code works fine. The actual problem was due to the destPath.

I was trying to provide the absolute path of the server eg: xyz/abc/inventory.txt

Instead all i needed to do was ./inventory.txt
