Validation error - query args escape_unicode error

The error arises in this code

File “/home/frappe/frappe-bench/apps/frappe/frappe/desk/doctype/event/event.py”, line 22, in validate
self.validate_overlap()
File “/home/frappe/frappe-bench/apps/frappe/frappe/desk/doctype/event/event.py”, line 43, in validate_overlap
validate_overlap_for(self, “Event”, “teacher”)

hence your post here Overlap validation

It seems the query is malformed due to encoding?

Perhaps confirm tabTeacher in fact has this Alaa_Badri

“AttributeError: ‘teacher’ object has no attribute ‘translate’”
