I just tried to upgrade from 6.3.0 to 6.4.0 and run into a few problems. After I purged the test database and reinstalled Flowable, I got the `Configuration for 'APP' is missing` error in the Catalina log (please have a look into the log file). It’s not documented how to solve this problem. What do I need to do to solve this? > ---

Hey @Heurazio, Do you perhaps have overridden the Flowable default properties on your side? I would advise you to have a look at the [`flowable-default.properties`](https://github.com/flowable/flowable-engine/blob/master/modules/flowable-ui-admin/flowable-ui-admin-app/src/main/resources/flowable-default.properties)` for the Admin application and compare it. I would also strongly advise you not to override the `flowable-default.properties`, but provide your own `application.properties`. Doing it this way you make sure not to miss some new defaults and also you can override any property as the `application.properties` have a higher precedence. Cheers, Filip
