Unable to programmatically create user

Question

I am trying to programmatically create a user in Drupal 8 using the following code.

$language = \Drupal::languageManager()->getCurrentLanguage()->getId();

$user = \Drupal\user\Entity\User::create();
$user->setPassword($form_state->getValue('pass'));
$user->enforceIsNew();
$user->setEmail('[email protected]');
$user->setUsername('test_test');
$user->set("init", '[email protected]');
$user->set("langcode", $language);
$user->set("preferred_langcode", $language);
$user->set("preferred_admin_langcode", $language);
$user->activate();
$user->save();

When I execute it, I get the following exceptions.

Drupal\Core\Entity\EntityStorageException: Field type is unknown. in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 783 of /home/printhouseheroes/public_html/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).
InvalidArgumentException: Field type is unknown. in Drupal\Core\Entity\ContentEntityBase->getTranslatedField() (line 586 of /home/printhouseheroes/public_html/core/lib/Drupal/Core/Entity/ContentEntityBase.php).

How can I avoid getting those exceptions?

Answer 1

The exceptions aren't caused from the code shown in the question. The second exception is caused from the following code in ContentEntityBase::getTranslatedField().

// Populate $this->fields to speed-up further look-ups and to keep track of
// fields objects, possibly holding changes to field values.
if (!isset($this->fields[$name][$langcode])) {
  $definition = $this->getFieldDefinition($name);
  if (!$definition) {
    throw new \InvalidArgumentException("Field $name is unknown."); // Line 586.
  }

  // Omissis.

}

There is a module that is trying to access the type field, which doesn't exist for the User entity.

Your code is correct. Eventually, instead of setting the user fields using a setter method, you could use the array User::create() accepts as first parameter, which uses the following array keys (among others):

• name
• mail
• pass
• status
• roles (an array)
• langcode
• preferred_langcode
• preferred_admin_langcode

There isn't an equivalent value for enforceIsNew(), so you need to call that method on the created user object.
