How to update with femanager (TYPO3)? - php

Question

I'm working on a project and my task is : set up a page to edit my user account information. For this, I have to use the TYPO3 extension femanager.
I installed the extension and put the plugin on my page. I have 4 fields that are displayed (photo, phone numbers and email). But when i submit my form, I have this error :
Argument 2 passed to
In2code\Femanager\Utility\FrontendUtility::forceValues() must be of
the type array, null given, called in
/home/dev/rta/htdocs/typo3conf/ext/femanager/Classes/Controller/EditController.php
on line 69
I tried to look for someone with a similar problem on the Internet but couldn't find anything. I looked at the code, but since it's the base extension code, I don't think that's where the problem comes from. The users are stored in the fe_users table in my database and the fields pre-fill nicely with my existing data.
I just learned TYPO3 3 weeks ago so I have a lot of gaps and I'm not very familiar with it yet.
If it can help, here is my EditController.php (lines 66 to 79) :
public function updateAction(User $user)
{
$this->redirectIfDirtyObject($user);
$user = FrontendUtility::forceValues($user, $this->config['edit.']['forceValues.']['beforeAnyConfirmation.']);
$this->emailForUsername($user);
UserUtility::convertPassword($user, $this->settings['edit']['misc']['passwordSave']);
$this->signalSlotDispatcher->dispatch(__CLASS__, __FUNCTION__ . 'BeforePersist', [$user, $this]);
if (!empty($this->settings['edit']['confirmByAdmin'])) {
$this->updateRequest($user);
} else {
$this->updateAllConfirmed($user);
}
$this->redirect('edit');
}
And here is my FrontendUtility class (used in my EditController at line 69) :
public static function forceValues(User $user, array $settings)
{
foreach ((array)$settings as $field => $config) {
$config = null;
if (stristr($field, '.')) {
continue;
}
// value to set
$value = self::getContentObject()->cObjGetSingle($settings[$field], $settings[$field . '.']);
if ($field === 'usergroup') {
// need objectstorage for usergroup field
$user->removeAllUsergroups();
$values = GeneralUtility::trimExplode(',', $value, true);
$userGroupRepository = self::getUserGroupRepository();
foreach ($values as $usergroupUid) {
/** #var UserGroup $usergroup */
$usergroup = $userGroupRepository->findByUid($usergroupUid);
$user->addUsergroup($usergroup);
}
} else {
// set value
if (method_exists($user, 'set' . ucfirst($field))) {
$user->{'set' . ucfirst($field)}($value);
}
}
}
return $user;
}
If anyone has an idea, I'm interested!
PS : I use TYPO3 v9.5.8
