TYPO3 Object of type xxx\\yyy\\Domain\\Model\\User with identity \"1\" not found."

Question

I want to add a custom FrontendUser to a group (not related to frontend group) in the groups controller.

Somehow Extbase can find my group by the uid but not the user I specified by uid.

My action in th GroupController is:

/**
  * action addUser
  * @param \xxx\Yyy\Domain\Model\Group $group
  * @param \xxx\Yyy\Domain\Model\User $user
  *
  * @return void
  */
  public function addUserAction(\xxx\Yyy\Domain\Model\Group $group, \xxx\Yyy\Domain\Model\User $user)
  {
    $group.addUser($user);
    return "ok";

  }

My error exception is:

{"error":"TYPO3\\CMS\\Extbase\\Property\\Exception\\TargetNotFoundException #1297933823: Object of type xxx\\Yyy\\Domain\\Model\\User with identity \"1\" not found."

For debugging purpose I added the an initializeAction:

public function initializeAddUserAction()
  {
    return var_dump($_POST);
  }

The result is:

array(1) {
  ["tx_yyy_jsonapi"]=>
  array(4) {
    ["controller"]=>
    string(5) "Group"
    ["action"]=>
    string(7) "addUser"
    ["group"]=>
    int(1)
    ["user"]=>
    int(1)
  }
}

What am I doing wrong? Why is the group resolving fine but the user not? I'm using TYPO3 8.7 with the rest extension in verion 3.

The fe_users had the field tx_extbase_type set to 0. It works if I set it to Tx_Yyy_User. So the problem was that I made no diffence between a regular FrontendUser and my custom frontend user.
