Sending file and JSON in a many-to-many relationship - spring

Question

I have a model called EPI that has a many to many relationship with Model Images, I am not able to do the #PostMapping for this object.
see my code
EPI Entity:
#Entity
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Table(name = "EPI")
public class EPI implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "Id_EPI")
private UUID id;
#Column(name = "Nome", nullable = false, length = 100)
private String nome;
#Column(name = "Marca", nullable = false, length = 100)
private String marca;
#Column(name = "CA", nullable = false, length = 100)
private String ca;
#Column(name = "Descricao", nullable = false)
private String descricao;
#Column(name = "Foto")
#ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinTable(name = "epi_images",
joinColumns = {
#JoinColumn(name = "epi_id")
},
inverseJoinColumns = {
#JoinColumn(name = "image_id")
})
private Set<ImageModel> foto;
#Column(name = "Quantidade", nullable = false)
private Integer quantidade;
}
Image Entity:
#Entity
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Table(name = "image_model")
public class ImageModel implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private UUID id;
private String name;
#Column(name = "type")
private String type;
#Column(name = "image_data", unique = false, nullable = false, length = 100000)
private byte[] imageData;
}
Controller EPI:
#PostMapping("/addNewEPI")
public ResponseEntity<Object> salvarFEPI(#RequestPart("image")MultipartFile file,
#RequestPart("epiModel") EPI epi) throws IOException {
try {
ImageModel foto = productImageService.uploadImage(file);
epi.setFoto((Set<ImageModel>) foto);
return ResponseEntity.status(HttpStatus.CREATED).body(epiService.save(epi));
} catch (Exception e){
System.out.println(e.getMessage());
return null;
}
Service Image:
public ImageModel uploadImage(MultipartFile file) throws IOException {
ImageModel image = new ImageModel();
image.setName(file.getOriginalFilename());
image.setType(file.getContentType());
image.setImageData(ImageUtility.compressImage(file.getBytes()));
return image;
}
As I am passing the parameters in Postman:

Return from Spring Boot:

If anyone can help me I would be very grateful!
I tried passing the parameters in different ways. I just want it to populate my tables passing the parameters of the EPI entity and the Image file.
