Error "Notice: Undefined property: stdClass::$field_..." on update from 2.0-alpha4 to beta 2

I had a similar issue with field_image
Undefined property: stdClass::$field_image_alt in Drupal\Core\Entity\Sql\SqlContentEntityStorage->loadFromDedicatedTables() (line 1288 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

The Error occurs when there is some column missing in the database table. In your case, the field_display_photos__title column is missing from the tables node_field_display_photos and node_revision_field_display_photos
and in my case the column name is field_image_alt so we need to add column first.

/**
* Adding missing columns field_image alt
*/
function custom_module_update_8003() {

  // Prepare relevant variables.
  $entity_type = 'node';
  $field_name = 'field_image';
  $field_length = 10;

  try {
    // Update database schema.
    $database = \Drupal::database();
    // Add column.
    $database->query("ALTER TABLE {$entity_type}__{$field_name} ADD COLUMN {$field_name}_alt VARCHAR({$field_length}) NOT null DEFAULT 0");
    // Add column to revision.
    $database->query("ALTER TABLE {$entity_type}_revision__{$field_name} ADD COLUMN {$field_name}_alt VARCHAR({$field_length}) NOT null DEFAULT 0");
  } catch (\Exception $e) {
    return $e->getMessage();
  }

  return t('alt column added.');
}

After that run update.php. After all this process you can delete the field and create new field with similar name.

Thanks

I'm occurring the same problem in two fields.

When I'm trying to edit fields settings:
Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'field_name

Warning code:
Warning: Undefined property: stdClass::$field_name in Drupal\Core\Entity\Sql\SqlContentEntityStorage->loadFromDedicatedTables() (line 1267 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

And yes, this the fields with '_argument' at the end.

After examining the viewsreference.install code I realized that problem was with the columns with _argument and _title at the end. This is the custom module code I've used to fix the problem:

/**
* Adding missing column 'argument' for field_name
*/
function field_fix_update_8100() {

  // Prepare relevant variables.
  $entity_type = 'node';
  $field_name = 'field_name_';
  $field_length = 10;

  try {
    // Update database schema.
    $database = \Drupal::database();
    // Add column argument.
    $database->query("ALTER TABLE {$entity_type}__{$field_name} ADD COLUMN {$field_name}_argument VARCHAR({$field_length}) NOT null DEFAULT 0");
    // Add column argument to revision.
    $database->query("ALTER TABLE {$entity_type}_revision__{$field_name} ADD COLUMN {$field_name}_argument VARCHAR({$field_length}) NOT null DEFAULT 0");
  } catch (\Exception $e) {
    return $e->getMessage();
  }

  return t('alt column added.');
}

/**
* Adding missing column 'title' for field_name
*/
function field_fix_update_8101() {

  // Prepare relevant variables.
  $entity_type = 'node';
  $field_name = 'field_name_';
  $field_length = 10;

  try {
    // Update database schema.
    $database = \Drupal::database();
	// Add column title.
    $database->query("ALTER TABLE {$entity_type}__{$field_name} ADD COLUMN {$field_name}_title VARCHAR({$field_length}) NOT null DEFAULT 0");
    // Add column title to revision.
    $database->query("ALTER TABLE {$entity_type}_revision__{$field_name} ADD COLUMN {$field_name}_title VARCHAR({$field_length}) NOT null DEFAULT 0");
  } catch (\Exception $e) {
    return $e->getMessage();
  }

  return t('alt column added.');
}

After enabling this module:

drush updb
yes
drush cr

Could you check if #2925609: Update viewsreference_update_8103 fails if table name is too long and shortened by Drupal solves the issue?
