Only variables should be passed by reference (array_shift)

Any news about this?

Ahh sorry, my bad. I will test and later i tell you still exist the issue.

Nope, the problem persist. When i change from:

// ... 
/**
   * @param array $tids
   *
   * @return array
   */
  public function getUserTermPermissionsByTids($tids) {
    $uids = [];

    foreach ($tids as $tid) {
      $uids[] = array_shift($this->getUserTermPermissionsByTid($tid));
    }

    return $uids;
  }
//...

to:

// ... 
/**
   * @param array $tids
   *
   * @return array
   */
  public function getUserTermPermissionsByTids($tids) {
    $uids = [];

    foreach ($tids as $tid) {
      $tmp = $this->getUserTermPermissionsByTid($tid);
      $uids[] = array_shift($tmp);
    }

    return $uids;
  }
// ...

I got the error on the next function which is:

// .. /**
   * @param array $tids
   *
   * @return array
   */
  public function getRoleTermPermissionsByTids($tids) {
    $rids = [];

    foreach ($tids as $tid) {
      $rids[] = array_shift($this->getRoleTermPermissionsByTid($tid));
    }

    return $rids;
  }
// ..

And when i switch to this:

// ... 
/**
   * @param array $tids
   *
   * @return array
   */
  public function getRoleTermPermissionsByTids($tids) {
    $rids = [];

    foreach ($tids as $tid) {
      $tmp = $this->getRoleTermPermissionsByTid($tid);
      $rids[] = array_shift($tmp);
    }

    return $rids;
  }
// ...

I got another different error:

Warning: array_flip(): Can only flip STRING and INTEGER values! in Drupal\Core\Entity\EntityStorageBase->loadMultiple() (line 227 of core/lib/Drupal/Core/Entity/EntityStorageBase.php).

But i think this is another issue... :/

Hey,

The error has gone, now can you close the issue. All good. Thanks for the great work.
