pymysql.err.OperationalError: (1054, “Unknown column ‘fee_schedule’ in ‘where clause’”)


I was tying to add a new fee structure but when I click on save it shows this error:

pymysql.err.OperationalError: (1054, “Unknown column ‘fee_schedule’ in ‘where clause’”)
Possible source of error: education (app)

App Versions

	"education": "15.2.1",
	"erpnext": "15.17.1",
	"frappe": "15.17.3",
	"healthcare": "16.0.0-dev",
	"hrms": "15.14.0",
	"payments": "0.0.1"

Any help is appreciated.
