Could not update Flowable database schema: unknown version from database: ''


I already read similar topics.

It looks like the reason is that flowable db version (accessible through ACT_GE_PROPERTY) is currently 6.6.1 while my flowable-spring-boot-starter is 6.6.0.

The issue is that flowable-spring-boot-starter 6.6.1 doesn’t exist.

Could you confirm that this is the core issue ?
How could I fix it ? I don’t find a way to change the db version to 6.6.0.


If you’re getting that exception, it means that you’ve ran a newer version of Flowable and then reverted back to an older version. The only way to fix that is to figure out which version you ran before and apply the reverse changes (which is not automatic).
