While working on a Drupal 8 project we suddenly encountered this error after pushing the site to the development server. This had not occurred in our local machines which caught us off guard. A little debugging on the error log revealed the cause of this Drupal message.

However, if you do not have access to the error log it and if the issue is only occurring in a particular server after deployment then it is most likely to be a DB issue.
