It seems there is some problem in this statement in the file student.py.

frappe.db.sql(
						"""UPDATE `tab{0}` set student_name = %s where {1} = %s""".format(
							d, linked_doctypes[d]["fieldname"][0]
						),
						(self.student_name, self.name),
					)

Any idea what is the mistake in this statement?

Hello,

I have not installed or used Education App but I think you need to replace the code as follows in file student.py @ line # 57:

field = meta.get_field(linked_doctypes[d]["fieldname"][0])
if field:
     frappe.db.set_value(d, self.name, "student_name", self.student_name)
