HTTP POST Returns 404 Not Found

I have a Spring Web MVC application with MongoDB, which stores files in Azure Blob Storage. When I send a POST request with a zip file to be stored in Postman I receive Status Code 404 Not found. My logs look like this:

I have the following classes:
CalibrationController.java

@Controller
public class CalibrationController {

    private final CalibrationService calService;
    private static final Logger log = org.apache.logging.log4j.LogManager.getLogger(CalibrationController.class);

    @Autowired
    public CalibrationController (CalibrationService calService) {
        this.calService = calService;
    }
  
    @PostMapping(path = "/upload", consumes = {MediaType.MULTIPART_FORM_DATA_VALUE})
      @ResponseBody
        public ResponseEntity<String> newBundle(@RequestParam("file") MultipartFile file) {
            log.info("Received a file to upload");
           Calibration created = calService.uploadBundle(file);           
           return ResponseEntity.status(HttpStatus.CREATED).body("Bundle was saved successfully with URI: " + created.getUrl());
           
    }
    
}

CalibrationInitializer.java

public class CalibrationInitializer implements WebApplicationInitializer{

   @Override
   public void onStartup(ServletContext ServletContext){
       // Load Spring web application configuration
      AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
      context.register(CalibrationServletConfig.class);

      // Create and register the DispatcherServlet
      DispatcherServlet servlet = new DispatcherServlet(context);
      ServletRegistration.Dynamic registration = ServletContext.addServlet("api", servlet);
      registration.setLoadOnStartup(1);
      registration.addMapping("/api/*");
   }
}

CalibrationServletConfig.java

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.example.prototype_mvc.databaseStorage.controller"})
public class CalibrationServletConfig {

        
}

I've tried to create the implementation for Dispatcher Servlet as a possible solution for this error because I was getting it also without the CalibrationInitialize.java and CalibrationConfig.java classes. So shouldn't my application run also without initialization and registration of Dispatcher Servlet, if I am having annotated controller? Shouldn't the annotations in the Controller.java class be recognized?
I really don't know what I am doing wrong. Any help would be useful!

  1. update application properties to
server.servlet.context-path=/api
  1. replace intializer with below
public class CalibrationInitializer implements WebApplicationInitializer{

   @Override
   public void onStartup(ServletContext ServletContext){
       // Load Spring web application configuration
      AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
      context.register(CalibrationServletConfig.class);
   }
}
