Flowable-ui-app.properties file not working

I actually saw that in a changelog a while back (don’t remember when) but had forgotten.
For those of you who run into this issue simply specify the useMysqlMetadata property in the datasource url as mentioned in that JIRA (spring.datasource.url=jdbc:mariadb://127.0.0.1:3306/flowable?useMysqlMetadata=true&characterEncoding=UTF-8) and that resolves the issue.
thank you @dbmalkovsky
