Database session - "Call to undefined method App\Session\Drivers\DatabaseSessionDriver::start()"

As per documentation, i am trying to implement a database driver due to issues with WPEngine, but i get the following error:

Deprecation notices related:

Configuration i set as shown below:

app.php

SessionProvider.php

DatabaseSessionProvider.php

session.php

Already tested troubleshoot mode (all plugins disabled) but the issue remains. Any help debugging the issue is welcome.

Hi @tcunhagwm I've not had time to dig deep into this, but I think the warnings you are seeing might be because your DatabaseSessionDriver.php file needs to have return types and typed parameters. For example:

public function read ($session_id) {}

should become:

public function read (string $session_id): string|false {}

This is something we are missing in the documentation - I will make a note to address it.
