Not a high priority as there's a simple solution... but 0.3.14 refuses to start up because spring.graphql.jpa.query.path is not defined. Which is odd because it is defined in default.properties which is referenced by GraphQLJpaQueryProperties. I have both graphql-jpa-query-autoconfigure and graphql-jpa-query-boot-starter as dependencies.
Simple workaround foe now is to add:
spring.graphql.jpa.query.path: /graphql
to the enclosing application's properties.
