Why can't this create a new file on the remote server? "no such file or directory"

The issue is present in the example code for me

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

sftp.connect({
    host: '...',
    port: '...',
    username: '...',
    password: '...'
}).then(() => {
    return sftp.fastPut('./test.txt', '/tf/maps/test.txt') //this doesn't work unless a '/tf/maps/test.txt' already exists which it will overwrite
    //return sftp.put(require(`fs`).createReadStream('./test.txt'), '/tf/maps/test.txt') //Same issue as above
    //return sftp.list('/tf/maps/') //This works
}).then(data => {
    console.log(data, 'the data info');
}).catch(err => {
    console.log(err, 'catch error');
});

I get the error Error: fastPut->exists->_stat: open /var/lib/pufferd/servers/18a5d777-a56d-4d07-a6f4-7d0e3f619081/tf/maps/test.txt: no such file or directory /tf/maps/test.txt for fastPut and put, unless I already have a test.txt on the remote server. Does this package only overwrite existing files? I have no idea how to actually create a remote file In the readme it says remotePath: string. Path to the remote file to be created on the server. which suggests that it should create the file yet refuses to write unless it’s already there.

I have the server open in Filezilla and am able to create files there so I don’t think it’s a permission issue. I have also tried explicitly giving the flag w , and tried different modes as if that would do anything

When I already made a blank test.txt

test.txt was successfully uploaded to /tf/maps/test.txt! the data info

Fix released in v5.2.2

Just looking more closely at the error message and the server code, can you verify the server supports the stat() method e.g.

sftp.stat(/path/to/remote/file’);

I suspect the command is not supportedor it is returning data in a non-comnpliant manner.

run the command with argument for a file which exists, a file which does not exist and a directory which exists. Send me the results.
