Frappe LMS Error when adding Course Lesson

Hello team. I had installed FrappeLMS on Frappe v.14 with ERPNext V14, but when I try to add Course Lesson, I get the following error when I press the save button.

pymysql.err.OperationalError: (1054, “Unknown column ‘course’ in ‘field list’”)

How can I solve this pls?
Thank you
