"RuntimeException: Unable to determine class for field type found in the configuration"

Question

I got this error while updating from Drupal 8.3.7 to Drupal 8.4.0.

RuntimeException: Unable to determine class for field type 'webform' found in the 'field.storage.node.webform' configuration in Drupal\field\FieldStorageConfigStorage->mapFromStorageRecords() (line 157 of core/modules/field/src/FieldStorageConfigStorage.php).

How can I fix this error?

Answer 1

One possible way is that your module is missing from the codebase or has been improperly uninstalled and you've still a field which is using that missing module.

Try the following drush/SQL commands to remove the broken field:

drush sqlq "DELETE FROM cache_config"
drush sqlq "DELETE FROM config WHERE name = 'field.storage.xxx.xxx' OR data LIKE '%field.storage.xxx.xxx%'"
drush sqlq "DELETE FROM config_snapshot  WHERE name = 'field.storage.xxx.xxx' OR data LIKE '%field.storage.xxx.xxx%'"

Warning: Don't execute above commands on master/live database. Make a backup before doing any database changes.

Where field.storage.xxx.xxx is your reported field storage type (e.g. field.storage.node.webform).

If above won't help, check for any other references by:

drush sql-dump --ordered-dump | grep field.storage.xxx.xxx

At the end you need to rebuild your caches:

drush cr

I had a similar error with another module (address in my case). I could fix it by simply re-install the concerned module with drupal console by the following command:

drupal module:install address

And back to business :)

Answer 3

When I see that error my trick is to try enabling the offending module again from the command line and then clearing cache. For example:

lando drush cr
