Cache rebuild causes an error with missing plugin On rebuilding the cache, a Drupal 8 website goes down and displays the message "The website encountered an unexpected error. Please try again later." I used drush cr to rebuild the cache, which shows the following error message.


  The "field_item:boolean" plugin does not exist.


I also tried to rebuild the cache right after installing a new Drupal 8 site without any additional module, and it shows the same error.

How can I get the site back to working?
This morning I had similar problem and drush cr was actually not clearing the discovery cache but after 

drush sql-query 'TRUNCATE TABLE cache_discovery;'


I was able to get rid of this error
