SFTP: FastGet returning Folder not found error

I’m having trouble downloading a file with the sftp fastGet method. Here is my code:

  var client = new Client();
  client.on('ready', function() {
    client.sftp(function(err, sftp) {
      sftp.fastGet('./file.zip', 'file.zip', function(err) {
        client.end();
      });
    });
  }).connect({
    *connection_info*
  });

I am getting the following error:

Error: Folder not found: \remote\pathHome\directory\file.zip

If I do a readdir: sftp.readdir('./', function(err, filelist) { console.log(filelist); });

It lists file.zip as one of the files.

And if I do a realpath: sftp.realpath('./', function(err, absPath) { console.log(absPath); });

It returns /home/directory (note the lowercase h on home)

I am not the administrator of the sftp server so can only assume that the \remote\path part of the error is some internal directory structure on the server.

Using node v4.2.1 and ssh2 v0.4.12

I’m having the same problem. If I use the .list() method, it gives me the list of files, but when I try to do a getFast, it says that the files do not exist.

This looks like it is ssh2-sftp-client, not ssh2?

At any rate, I suspect you have a bug in your code. In the then block of your promise chain, the call to client.fastGet() needs to be proceeded with a return statement. Without the return statement, your actually starting a whole new promise chain. In your original code, because the fastGet() call was in its own promise chain, the client.end() call was occurring before the fastGet() call was fulfilled. The client.end() call knows nothing about the fastGet() call as it is in a separate chain, so does not wait for it to be fulfilled. Removing the call to end allows the fastGet() call to be fulfilled, but now you have no way of knowing when the work is done and can close the connection. Add the return statement and the call to client.fastGet() becomes part of the promise chain, so client.end() will wait until it is fulfilled before ending the connection.

Change your code to

let remotePath = './pix2pix-tensorflow/invokator_test/images/001-outputs.png';
let localPath = './001-outputs.png';

client.connect(config)
    .then(() => {
        return client.fastGet(remotePath, localPath);
    })
    .then(() => {
       return client.end();
     })
    .catch(err => {
        console.error(err.message);
    });
