Remove Roles From User

I’m trying to create code to add a Role to a user

$auth = Yii::$app->authManager;
$role = $auth->getRole('User');
$auth->assign($role, $this->id);

This works fine.

But I also need code to remove a Role or all Roles and can’t seem to get anything to actually work.

$auth = Yii::$app->authManager;
$role = $auth->getRole('User');
$auth->revoke($role, $this->id);
$auth = Yii::$app->authManager;
$auth->revokeAll($this->id);

Neither work, what am I doing wrong?

This is part of my user model beforeSave/afterSave.

    public function beforeSave($insert)
    {

        $auth = Yii::$app->authManager;

        if (!parent::beforeSave($insert)) {
            return false;
        }

        // if (!$this->isNewRecord) {

        // }
        if (!$insert) {
            if ($this->status == self::STATUS_DELETED) {
                // Deactivating the user
                $role = $auth->getRole('User');
                $auth->revoke($role, $this->id);
            }
        }
        return true;
    }

I should also note that I’m using GitHub - mdmsoft/yii2-admin: Auth manager for Yii2 (RBAC Manager) if that changes anything.

What I don’t get is even if I remove the conditions, so it should always run, the role is never revoked?!
