InvalidArgumentException: The state '' does not exist in workflow

Since this has been in PNMI for 11 months going to close out for now.

If still a valid bug though please reopen updating the issue summary with steps to trigger this error.

Tried enabling the workflow module but I don't see any issue for what it's worth.

Thanks all!

Getting the same error

InvalidArgumentException: The state '' does not exist in workflow. in Drupal\workflows\Plugin\WorkflowTypeBase->getState() (line 155 of core/modules/workflows/src/Plugin/WorkflowTypeBase.php).

Steps to reproduce:

under "this workflow applies to" select article, basic page or any content type at /admin/config/workflow/workflows/manage/editorial
then visit node/add/article or node/add/pager you will get WSOD with the following error

Drupal 10.1.4
PHP 8.2.6
content_moderation: 10.1.4
workbench_moderation: 8.x-1.7

It seemd the error occured when an AJAX operation occured.

I got the same error message when I was trying to preview a new node that had content moderation enabled. The source of the issue was a bug 🐛 Had an issue with preview button Needs work in the workflow_buttons → module.
