The solution is to mount a sessions folder into Platform.sh and write sessions in that folder.
Simply edit your
.platform.app.yaml and add a mounts there:

ini_set('session.save_path', __DIR__.'/../app/sessions' );

cd my_project_name/ composer install
If you get the following error during a deploy hook:

This means that you might have committed the executable file (in this case
app/console) without the execute bit set.
Run this to fix the problem:
chmod a+x app/console git add app/console git commit -m "Fix the console script execute permission."
