A non-existent config entity name returned by FieldStorageConfigInterface::getBundles():

Full error (Views):
A non-existent config entity name returned by FieldStorageConfigInterface::getBundles(): entity type: node, bundle: article, field name: body

Some suggestion from people:-

1) Delete the table from database: https://www.drupal.org/project/drupal/issues/2916266#comment-12480829
Using this command (but must make a backup!):-
SELECT * FROM `key_value` WHERE `value` LIKE '%comment_node_gallery_item%
Note: red color - replace with the error

2) Adding that field : https://www.drupal.org/project/drupal/issues/2916266#comment-12706880
In my case, 'body' is not in Article content type but the report say that 'body' used in Article ! (Go to /admin/reports/fields) - This list shows all fields currently in use for easy reference
