I’d got this error too. For me the solution was to modify the post attribut of my maintenance mode model and select elementor canvas. Hope this help !
@nuggetsol thank you so much! Now it works!
Nop, same issue. But if I set it as false it works well with the old editor.
Hi @nuggetsol,
thanks for your reply. I’m afraid that it’s still not working. I still get this error after saving CPT config and “Show in rest API” set to true. If i disable Oasis Workflow plugin the problem disappears.
