I am trying to run my SpringBoot application to check some changes I did in one of the controllers and I am getting the following error
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'inboxApp': Unsatisfied dependency expressed through field 'folderRespository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'folderRepository' defined in io.inbox.folders.FolderRepository defined in @EnableCassandraRepositories declared on InboxApp: Cannot resolve reference to bean 'cassandraTemplate' while setting bean property 'cassandraTemplate';

However, since I did some minor modifications in my code I cannot run the app anymore... Could you please tell me what do you think is generating this error? As you will see, my classes are super simple and I think everything is being done properly. Thanks for your time.
