Problems with Micronaut Data

Question

I am currently in the process of upgrading an existing Micronaut application from version 1.2.x to 2.2.1 (latest) and I thought that it would also be a good idea to start using micronaut-data to perform whatever database interactions are required.

I have implemented all the various code changes and have also ported the code over to use Micronaut's own repositories but whenever I start the application, every time it attempts to perform any kind of database-related interaction it fails with the following error:

20:21:06.535 [scheduled-executor-thread-21] ERROR i.m.s.DefaultTaskExceptionHandler - Error invoking scheduled task for bean [fts.marketing.utils.$TestDefinition$Intercepted@122b3da3] No bean of type [io.micronaut.transaction.SynchronousTransactionManager] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

I have followed the configuration guide found here regarding setting up Micronaut Data and I think I have imported all the correct dependencies https://micronaut-projects.github.io/micronaut-data/latest/guide/#introduction.

Documentation states that a transaction manager should be available automatically but this seems not to be the case.

For reference my build.gradle and application.yml looks like so:

Does anyone have a hint as to why this problem occurs?
