type error on drush cr

This change is correct. Try to clear your caches.

It is when I clear caches (drush cr) that I get the error.

I don't know how you performed your update.

I just updated another installation and drush cr worked fine. The command helpers are services. It seems that you have overwritten the module's service definition.

I can't reproduce the issue in any production environment I maintain. Maybe you use some custom code or third party module that needs to apply these constructor changes.

Automatically closed - issue fixed for 2 weeks with no activity.

It looks like it's a permission issue. I also got this error after updating. Everything worked fine in DDEV after the update, but after pushing the update to the server, I got the error after running drush updatedb, drush uli and drush cache:rebuild.

I also saw an odd error about assets:

$ drush updatedb
 [success] No pending updates.
 [warning] unlink(/var/www/html/website/public_html/web/sites/default/files/css/css_Dd8YCdHfaQEgt3dWdSVw94rP7EmTUdfBCOWw7Z_fzr8.css): Permission denied FileSystem.php:124

It looks like Drupal updated the permissions for css and js folders after the update, from the original webuser:www-data to www-data:www-data:

$ ls /public_html/web/sites/default/files/
[...]
drwxrwxr-x 2 www-data www-data 4,0K Aug 10 13:34 css
drwxrwxr-x 2 www-data www-data 4,0K Aug 10 14:13 js
drwxrwx--- 3 webuser  www-data 4,0K Aug 10 12:46 php

I restored the permissions → , and all Drush commands now work again, without errors:

$ cd /public_html/web
$ chown -R webuser:www-data .
