I create nodes, which have a taxonomy field, like this:

$node = Node::create([   'type' => 'article',   'status' => 1,   'title' => 'Some title',   ...   'field_taxonomy' => [1, 2, 3], ]); $node->save(); 

The nodes are saved and can be displayed. But the views, which should display articles with selected taxonomy terms, return the following error message:

If I manually open the editing form for every of the new nodes and save the node (without changing anything), then the error message disappear and the views display correct content. Resaving all new articles in a bulk operation or clearing all caches do not solve the issue.

The line 149 in /core/modules/taxonomy/src/Plugin/views/field/TaxonomyIndexTid.php looks like:

127 public function preRender(&$values) { 128     $vocabularies = $this->vocabularyStorage->loadMultiple(); ... 144     foreach ($result as $node_nid => $data) { 145         foreach ($data as $tid => $term) { ... 149             $this->items[$node_nid][$tid]['vocabulary'] = $vocabularies[$term->bundle()]->label(); ...             }         }     }
