phpseclib put returns true but file is not uploaded

Question

Using the PHP plugin phpseclib v2.0.18 with PHP 7.3, when I try to upload a file to the SFTP server, the put() method returns true, but the file is never uploaded.

The log say that everything is ok.

My code:

foreach ($schedules as $idx => $schedule)
{
    $company = \Company::getItem($schedule->id_login);

    $outgoing_path = concat_path(BASE_PATH, 'pdf', 'file_schedules', $company->cif, 'outgoing', date('Ymd'));

    if (!is_dir($outgoing_path)) create_folder($outgoing_path, 0775, true);

    if ( ! ($sftp = new SFTP($schedule->host, $schedule->port)))
    {
        static::logError('No se pudo iniciar la conexión.', array($schedule->id_login, $company->name, $company->cif));
        continue;
    }

    if (!$sftp->login($schedule->user, $schedule->password))
    {
        static::logError('No se pudo hacer login en el servidor remoto.', array($schedule->id_login, $company->name, $company->cif));
        continue;
    }

    unset($schedule->password);

    if (!$sftp->chdir(concat_path($schedule->path, 'outgoing')))
    {
        static::logError('No se pudo acceder al directorio.', $schedule);
    }

    $dir_iterator = new \DirectoryIterator($outgoing_path);

    $count = 0;

    foreach ($dir_iterator as $file)
    {
        if ($file->isDot()) continue;

        if ($sftp->put($file->getPathname(), concat_path($sftp->pwd(), $file->getFilename(), SFTP::SOURCE_LOCAL_FILE)))
        {
            $count += 1;
        }
    }

    static::logInfo("$count archivos exportados.");
}

Login is fine. The local and remote paths and filenames are both fine. Similar code for download files works fine. File permissions are fine.

What am I doing wrong?

The log output:

Seems to be alright.

Answer 1

From your code:

        if ($sftp->put($file->getPathname(), concat_path($sftp->pwd(), $file->getFilename(), SFTP::SOURCE_LOCAL_FILE)))
        {
            $count += 1;
        }

Let's break that down some. So you're doing this:

$sftp->put(
    $file->getPathname(),
    concat_path($sftp->pwd(), $file->getFilename(), SFTP::SOURCE_LOCAL_FILE)
);

idk what concat_path does but my guess is that you have the placement of the parenthesis wrong. My guess is that you want to be doing this:

$sftp->put(
    $file->getPathname(),
    concat_path($sftp->pwd(), $file->getFilename()),
    SFTP::SOURCE_LOCAL_FILE
);

Anyway, where are you looking for the files? Per your logs they should be showing up at /Users/jorge/MEGAsync/workspace/tesoriza/milestones/pdf/file_schedules/A86212420/outgoing/20191007/Prueba.xlsx . Is that where you're looking?
