Error on the new SQL stuff

Connecting to: https://soutien.dev.laquadrature.net/perso give me the follwing error:

Argument 1 passed to LQDN\Finder\AddressFinder::findByUserId() must be an instance of LQDN\Finder\int, string given, called in /srv/soutien/soutien/app/Perso.php on line 61 and defined [...]

It seems there's an issue on the type of data received by the sanitized_form (which gives me an int) and what the Container is waiting for.

The incriminated line is:

$addresses = $f3->get('container')['address_finder']->findByUserId($data['id']);

$data is the result of a SQL Query, so data[id] is probably not casted the correct way.
