Following the latest Spring Boot instructions, I’m attempting to use the flowable-spring-boot-starter. I’ve done it a couple times now and receive the following error:

My first attempt was using postgresql and I ran into this, I wanted to reduce the number of variables so I redid it using H2 (which yielded the same issue).
My pom references for both sprint boot and flowable…
