-Also, make sure you are not setting the Hibernate dialect explicitly, in other words remove any lines similar to:

-On some systems, it might be necessary to override hibernate's default naming strategy. The naming strategy must be set using spring.jpa.hibernate.physical_naming_strategy.

-On linux systems or when using docker mysql containers, it will be necessary to review the case-sensitive setup for
-mysql schema identifiers. See  https://dev.mysql.com/doc/refman/8.0/en/identifier-case-sensitivity.html. We suggest you
-set `lower_case_table_names=1` during mysql startup.
