I started with docker-compose the flowable-rest-app pointing to my postgres db (used by flowable-all-in-one), but it returns this error while starting tomcat:
Could not update Flowable database schema: unknown version from database: ‘6.5.0.0’
Could it be that you have a postgres db running the latest Github master version of Flowable?
The docker images will use the latest released version of Flowable and won’t know about version 6.5.0.0.
