Java spring POST request status 404

Question

I'm following a tutorial and my POST request is getting a 404 response. I dont understand why.

I have rewatched the tutorial many times and compared with another project and still can't find the error.

I appreciate all the help possible

PersonController:

import model.Person;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import service.PersonService;

@RestController
@RequestMapping(path = "api/v1/person")
public class PersonController {

    private final PersonService personService;

    @Autowired
    public PersonController(PersonService personService) {
        this.personService = personService;
    }

    @PostMapping
    public void addPerson(@RequestBody Person person){
        personService.addPerson(person);
    }
}

Service:

import dao.PersonDao;
import model.Person;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

@Service
public class PersonService {

    private final PersonDao personDao;

    @Autowired
    public PersonService(@Qualifier("fakeDao") PersonDao personDao) {
        this.personDao = personDao;
    }

    public int addPerson(Person person){
        return personDao.insertPerson(person);
    }
}
