I have a Java application that connects to a Denodo instance with JPA, using the denodo driver and dialect. After I upgraded the application to Spring version 3.1.2, Hibernate can't load the dialect anymore.
**Setup:**
Java 17
Spring Boot 3.1.2
Hibernate: 6.3.1
Denodo Driver: 8.0.202303011
Denodo Dialect Version: 8.0-20201021
**Spring configuration:**
spring.datasource.driver-class-name: com.denodo.vdp.jdbc.Driver
spring.datasource.url: jdbc:vdb://<myDenodoInstance>/<myDatabase>
spring.datasource.username: <username>
spring.datasource.password: <password>
spring.jpa.properties.hibernate.dialect: com.denodo.connect.hibernate.dialect.DenodoDialect
**Error message:**
org.hibernate.boot.registry.selector.spi.StrategySelectionException: Unable to resolve name [com.denodo.connect.hibernate.dialect.DenodoDialect] as strategy [org.hibernate.dialect.Dialect]
Has anyone already seen such cenarion?

I am trying to create an environment in vcs management (Denodo 8), first I created a github repo and cloned it locally.
In the configuration screen under VCS management in Denodo administration tool I added the url of this repo and the username and password of my github account.
In Environment screen, when I try to create a new environment I get an error that **I am not authorized**
when I try again I get another error which is:
