Error Upgrading MySQL 5.7 to 8.0 MySQL 8.0 syntax check for routine-like objects

2. MySQL 8.0 syntax check for routine-like objects https://dev.mysql.com/doc/refman/8.0/en/keywords.html More Information: https://dev.mysql.com/doc/refman/en/keywords.html mysql.flush_rewrite_rules - at line 5,8: unexpected token 'QUERY'

Above is my error message in PrePatchCompatibility file when I upgrade mysql from 5.7 to 8.0. But I can't find where the problem is to fix it. After doing research, I learned that there are people like me and they have to ask AWS support to drop them for them. How can I solve this problem?
