Extended fe_user model, can't access crdate when run via cronjob - cron

Question

I have a problem with accessing the crdate of a fe_user in a croniob task. I have an extended Frontend user model where I added this adjustments:
https://stackoverflow.com/a/50663006/1684975
Additionaly I've added a mapping via ts
config.tx_extbase {
persistence {
classes {
TYPO3\CMS\Extbase\Domain\Model\FrontendUser {
subclasses {
Tx_MyExt_User = ACV\MyExt\Domain\Model\User
}
}
Paul\MyExt\Domain\Model\User {
mapping {
tableName = fe_users
recordType = Tx_MyExt_User
columns {
crdate.mapOnProperty = crdate
}
}
}
}
}
}
When I fire up the Scheduler task manual via the Scheduler BE module it's ok. But when the real cronjob kicks in I get the error
Uncaught TYPO3 Exception Call to a member function getTimestamp() on null
In the Scheduler task, I get the crDate via the getter and try to get the timestamp…
$users = $frontendRepository->findByOptIn(false);
foreach ($users as $user) {
if ($user->getCrdate()->getTimestamp() < strtotime('-5 days')) {
$frontendRepository->remove($user);
}
}
The mode of the user is correct. I can access other custom properties I've added to the model.
It's TYPO3 v9.5.26.
The odd thing is that it runs locally in my dev environment.
Did someone have an idea what could cause the problem?

Add a file <extensionfolder>/ext_typoscript_setup.typoscript and add your TypoScript in there:
config.tx_extbase {
persistence {
classes {
TYPO3\CMS\Extbase\Domain\Model\FrontendUser {
subclasses {
Tx_MyExt_User = ACV\MyExt\Domain\Model\User
}
}
Paul\MyExt\Domain\Model\User {
mapping {
tableName = fe_users
recordType = Tx_MyExt_User
columns {
crdate.mapOnProperty = crdate
}
}
}
}
}
}
Alternativly you can add an include there to your TypoScript file in your extension Configuration/TypoScript folder.
If you are in CLI Context, it can be that the TypoScript is not loaded fully for the mapping/extbase configuration, which would match your description that in the BE Context it works, but not in Cronjob/CLI Context.
