java.lang.IllegalArgumentException: Target object must not be null - spring

Question

I'm getting this error when trying to insert a charity, because when doing /admin/charity/new/submit the charity object is null. I didn't have any problem inserting countries, I'm not an expert in spring-thymeleaf but it seems that i'm not trying well the many-to-one relationship.
I'm using Spring Data JPA.
Model:
#Getter #Setter #EqualsAndHashCode #ToString #NoArgsConstructor
#Entity
#EntityListeners(AuditingEntityListener.class)
#Table(name = "charities_table")
public class Charities {
#Id
#GeneratedValue
private Long id;
private String name;
private String logo;
private Double moneyRaised;
#ManyToOne
private Country country;
#Lob
private String description;
public Charities(String name, String description, String logo, Country country, Double moneyRaised) {
super();
this.name = name;
this.description = description;
this.logo = logo;
this.country = country;
this.moneyRaised = moneyRaised;
}
}
Controller:
#Controller
#RequestMapping("/admin/charity")
public class CharitiesController {
#Autowired
CharitiesService charitiesService;
#Autowired
CountryService countryService;
#ModelAttribute("charities")
public List<Charities> charitiesList() {
return charitiesService.findAll();
}
#ModelAttribute("countries")
public List<Country> countriesList() {
return countryService.findAll();
}
#GetMapping({"/","/list"})
public String list(Model model) {
model.addAttribute("charities", charitiesService.findAll());
return "admin/charity/list";
}
#GetMapping("/{id}/delete")
public String delete(#PathVariable Long id) {
Charities charityToDelete = charitiesService.findById(id);
charitiesService.delete(charityToDelete);
return "redirect:/admin/charity/list";
}
#GetMapping("/new")
public String newCharityForm(Model model) {
model.addAttribute("charity", new Charities());
model.addAttribute("countries", countryService.findAll());
return "admin/charity/form";
}
#PostMapping({"/new/submit", "/edit/submit"})
public String newCharitySubmit(#ModelAttribute Charities charity) {
charitiesService.insert(charity);
return "redirect:/admin/charity/list";
}
#GetMapping("/{id}/edit")
public String editCountryForm(Model model, #PathVariable Long id) {
Charities charityToEdit = charitiesService.findById(id);
model.addAttribute("charity", charityToEdit);
model.addAttribute("countries", countryService.findAll());
return "admin/charity/edit";
}
}
And here is the view:
<div class="container">
<div class="row">
<div class="col-md-offset-3 col-md-6">
<form method="post" action="#" th:action="#{/admin/charity/new/submit}" th:object="${charity}">
<h1>New Charity</h1>
<input type="hidden" id="id" name="id" th:field="*{id}" />
<div class="form-group">

</div>
<div class="form-group">
<label for="logo">Logo</label> <input type="text" class="form-control" id="logo" placeholder="Logo" th:field="*{logo}" />
</div>
<div class="form-group">
<label for="moneyRaised">Money Raised</label> <input type="number" class="form-control" id="moneyRaised" placeholder="Money Raised" th:field="*{moneyRaised}" />
</div>
<div class="form-group">
<label for="country">Country</label>
<select th:field="*{country}" id="country" class="form-control">
<option th:each="country: ${countries}" th:value="${country.id}" th:text="${country.name}"></option>
</select>
</div>
<div class="form-group">
<label for="description">Description</label> <textarea class="form-control" id="description" placeholder="Description" th:field="*{description}"></textarea>
</div>
<button type="submit" class="btn btn-default">Save</button>
</form>
</div>
</div>
</div>
