Start steps: error when trying to play can't stop

[Megazob]

Hello,
I've recently joined BGA Studio and when embarking for the "start steps" I've found a bug when trying to play Can't Stop:

Bad argument type: withAi should be a Number (positive integer) ()

#0 /var/tournoi/release/tournoi-200428-1120/www/action/table/table.action.php(752): APP_Action->getArg('withAi', 1, false, NULL)
#1 /var/tournoi/release/tournoi-200428-1120/www/include/webActionCore.inc.php(135): action_table->sologameExpressCreate()
#2 /var/tournoi/release/tournoi-200428-1120/www/index.php(230): launchWebAction('table', 'action_table', 'sologameExpress...', false, false, NULL, true, false)
#3 {main}
