I have the same warning
Limesurve: v3.25.19

config:

routes' => [
   'fileError' => [
      'class' => 'CFileLogRoute',
      'levels' => 'warning, error',
   ],
],

Please assign the task to someone else (currently working).

Thank you for reminder !

What fo severity for you ? partial_block ?

Yes, you can call it a partial block as the warning is logged every time the page is refreshed. And unfortunately it generates large files as a result.

I have files set to "Errors_YYYY-MM-DD.log;" so limiting the size and number of files is not a solution for me.

You surely can have an except value to disable this error :)

Maybe 'except'=>'system.db.ar.*', ?
(but disable log on activerecord … it's really NOT a solution)

Adding 'system.db.ar.*' to exclusions does not work. I still have this message in my logs.

@alorenc I think maybe the the upgrade installation flubbed the Tutorials database entry.

Quick hack. change models/Tutorial.php so that setAttributes is passed with 'false'. This will suppress the error. I don't see any knock-ons from this, but I'm just a user.

public function getDefaultTutorials()
{
$aDefaultTutorials = LsDefaultDataSets::getTutorialData();
$result = [];
foreach ($aDefaultTutorials as $aDefaultTutorial) {
$oTutorial = new Tutorial();
$oTutorial->setAttributes($aDefaultTutorial, false);
$result[] = $oTutorial;
}
return $result;
}

The most appropriate would be to add a rule for the 'settings' attribute of the Tutorial model (it's a json), but it seems to me that this functionality of the tutorials was not developed further, so I don't know if it makes sense.
