Email sending requires a composer call

[Signum]

I am using version 8.0.2 of the community edition. When users share a directory and send a link they keep getting "require_once(): Failed opening required 'vendor/autoload.php'" as a popup.

The web server log reads:

PHP Fatal error: require_once(): Failed opening required 'vendor/autoload.php' (include_path='…') in /srv/www/pydio.example.org/plugins/mailer.phpmailer-lite/PhpMailLite.php on line 53, referer: https://pydio.example.org/ws-my-files/

The solution for me was:

cd …/plugins/mailer.phpmailer-lite
composer install

That lead to:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 1 install, 0 updates, 0 removals
  - Installing phpmailer/phpmailer (v5.2.22): Downloading (100%)         
phpmailer/phpmailer suggests installing league/oauth2-google (Needed for Google XOAUTH2     authentication)
Writing lock file
Generating autoload files

Problem fixed. So it seems that the distributed archive is missing something.

I personnally reproduce on v6.2
