Updated Drupal from 8.7.8 to 8.8.0 with:

composer update --with-dependencies

That part went well, but when I run:

drush updb

I get following error:

In ProcessBase.php line 188:

  Unable to decode output into JSON: Syntax error                                                                             

  Error: Call to a member function getConfigDependencyKey() on null in Drupal\taxonomy\Plugin\views\filter\TaxonomyIndexTid-  
  >calculateDependencies() (line 394 of /var/www/html/drupal/web/core/modules/taxonomy/src/Plugin/views/filter/TaxonomyIndex  

Checked the code a bit and it goes like:

  public function calculateDependencies() {
    $dependencies = parent::calculateDependencies();

    $vocabulary = $this->vocabularyStorage->load($this->options['vid']);
    $dependencies[$vocabulary->getConfigDependencyKey()][] = $vocabulary->getConfigDependencyName(); // <-- line 394


And $this->options['vid'] is empty and $vocabulary var becomes null.

Any idea what's wrong here?


just to make you aware in case you're using the Pathauto module and you didn't notice:

Changes to path aliases and a critical note for sites using the Pathauto contributed module If you have the contributed Pathauto module enabled, you must update to the latest version of Pathauto before you update to Drupal 8.8.0. Failure to update Pathauto before updating core could result in data loss. Drupal 8.8.0 declares a conflict with Pathauto 8.x-1.5 or lower for this reason.


Can't say anything about your specific error though.

  • I didn't install it on my own. I don't have it on "Extend" admin page nor in composer.json file. But inside composer.lock I do have it under "conflict" section. But I guess that's ok? – MilanG Dec 5 '19 at 10:45
  • The conflict section just says there is a conflict between two packages. Drupal 8.8 reports it conflicts with Pathauto module versions prior to 8.x-1.6. – kiamlaluno Dec 5 '19 at 11:45
