NameError: name 'ceo_approval' is not defined

ceo_approval is an customized field in form sales order. we run this for quite a long time without issue until now.

frappe version: 12.16.3
erpnext version: 12.19.0
Thanks.

The issue has been resolved by myself after double check all conditions in workflow.
The root cause is the syntax error in one condition setup.
Use doc.ceo_approval instead of ceo_approval fix the problem.
