I'm trying to run prisma against an existing postgres instance to see what kind of datamodel it comes up with. However, the docker image seems to be stuck in some kind of restart loop. When I look in the docker logs, this is what I see over and over:

Exception in thread "main" java.lang.RuntimeException: Unable to load Prisma config: com.prisma.config.InvalidConfiguration: Expected Boolean for field active, got <unset>
	at scala.sys.package$.error(package.scala:27)

Any clues?
