Migrate problem v11 to v12

I get the error when I run the migrate command for my site. Any idea?

pymysql.err.IntegrityError: (1062, “Duplicate entry ‘‘TARGET’’ for key ‘PRIMARY’”)

raise raise_exception(msg)

frappe.exceptions.DoesNotExistError: DocType Call Log not found

After migrate comand now I get this error

More context please - post the full traceback

That will give all here more clues to your problem

Thank you for response. After I try lot of solutions that
mentioned here I give up. So I’ll continue with v10 for now. Thanks
