Feeds import of metatag entity_type

Sounds like a bug in the metatag module. Moving this issue to that project.

What version of Feeds is being used? There was a bug fixed in 1.3 (#2347193: Feeds integration borken in 1.0)?

I recently started experiencing this with Feeds 7-x-2.x-alpha8+71-dev. What I'm seeing is that the meta tag gets written to the node as an indexed array instead of a single value. This is visible using Devel. Additionally, the imported meta tags do not display in the markup.

I get something like this (the value element is an array and it should be a string):
$node->metatags['und']['og:image']['value'][0] (String')

After editing and saving the imported node manually (without changing anything), the error goes away, in particular the error with the token.

I was in a hurry and needed a one off fix for a content import so I hacked the metatag.feeds.inc file at the bottom. In my case, I only needed a single metatag so I knew what kind of data was going through that $value.

  // Assign the value.
  $langcode = metatag_entity_get_language($entity_type, $entity);
  // convert the $value to a string and prevent empty imports (which prevent global metatag inheritance)
  $value = implode (' ' , $value );
  if (!empty($value)) {
    $entity->metatags[$langcode][$name]['value'] = $value;
  }

The problem in #4 looks related, but has a different cause. In the dev version of Feeds, the "value" in the mapping target callback is now always an array. This is done to provide consistency across all mappers. See the change record: https://www.drupal.org/node/2301995
This change doesn't exist in Feeds 7.x-2.0-alpha8, which beauregard reports he/she is using that.

The problem in #0 seems to be caused by having the following condition FALSE:
if (!isset($entity->metatags) && !empty($entity->feeds_item->entity_id) && is_numeric($entity->feeds_item->entity_id)) {
Because after this code the variable $entity_type is used, but if the condition above results into FALSE this variable is undefined.

I ran into this issue as well. #6 brings out the correct issue. It seems that when you have an existing entity with metatag data. $entity_type does not get set.

Attached is a patch that brings the entity_type variable out of the if statement as we use it later no matter what.

Could you do a feed export and give a a dummy csv? That way we can test exactly what your doing. I have noticed something like this in the past if your csv is not saved using UTF-8. Without testing it though I am unsure.

comment #8 fix the issue. I've unfortunately missed this ticket and created my own one with exactly same fix :)
