[documents-service] org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread.

In documents-service, when a policy is paid, an error is raised: org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread. I've added the policy template in JSReport and committed.

Thanks for reporting. I'll try to have a look at it during next weekend.

Thanks for the feedback.
The good news is that I just fixed it by adding the following lines to the pom.xml of documents-service.

        <dependency>
            <groupId>io.micronaut.data</groupId>
            <artifactId>micronaut-data-hibernate-jpa</artifactId>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>io.micronaut.data</groupId>
            <artifactId>micronaut-data-processor</artifactId>
            <scope>compile</scope>
        </dependency>

And the error disappeared.
