Problem Upgrading MySQL 5.7 to 8.0

Hi!

I tried to migrate my MySQL instances but the problem is stored procedure "mysql.flush_rewrite_rules" in mysql database. I tried to remove it but I can't do that. Does anyone have any solution to that?

This is the result of util.checkForServerUpgrade();

2. MySQL 8.0 syntax check for routine-like objects The following objects did not pass a syntax check with the latest MySQL 8.0 grammar. A common reason is that they reference names that conflict with new reserved keywords. You must update these routine definitions and quote any such references before upgrading. More information: https://dev.mysql.com/doc/refman/en/keywords.html

mysql.flush_rewrite_rules - at line 5,8: unexpected token 'QUERY'
