spring-boot rest delete http java

I'm upgrading from an older version and I've looked through the documentation and I'm still confused about I'm developing a REST API using Spring Boot 2.6.4, and I'm working with a `500 Internal Server behavior` when I send a DELETE request to remove a resource from my database. The DELETE method is correctly mapping to my controller, but I'm not sure why it's failing. Here’s the relevant portion of my controller code: ```java @RestController @RequestMapping("/api/resources") public class ResourceController { @Autowired private ResourceService resourceService; @DeleteMapping("/{id}") public ResponseEntity<Void> deleteResource(@PathVariable Long id) { resourceService.deleteResource(id); return ResponseEntity.noContent().build(); } } ``` In the `ResourceService`, I'm calling the repository to delete the resource: ```java @Service public class ResourceService { @Autowired private ResourceRepository resourceRepository; public void deleteResource(Long id) { resourceRepository.deleteById(id); } } ``` I’ve checked the following: 1. The resource with the given `id` exists in the database prior to the DELETE request. 2. I’m sending the DELETE request using Postman without a body, as DELETE requests typically don’t require a request body. 3. My database connection is established and working for GET and POST requests. However, whenever I try to delete a resource, I get the behavior: ``` 500 Internal Server behavior Type: org.springframework.dao.EmptyResultDataAccessException Message: No class com.example.Resource entity with id null exists! ``` Could this be related to how Spring handles DELETE requests? Is there something I’m missing in the configuration? Any insights would be greatly appreciated. Thanks in advance for your help! I'm working on a service that needs to handle this. What am I doing wrong? I recently upgraded to Java 3.11. Cheers for any assistance!
