'Java REST POST using Apache Client Issue

I am trying to create a web client to trigger my web service POST method that deals with a multipart request. The first part of the request deals with sending a name in JSON format, and then the second part is adding a file to submit. Any assistance would be greatly appreciated.

So I have the below service.

@RequestMapping(path = "/senddata", method = POST, consumes = { MediaType.MULTIPART_FORM_DATA_VALUE })
public ResponseEntity<Object> process(@RequestPart("person") Person person,
@RequestPart("document") MultipartFile document) {

        System.out.println("/senddata called...");
        System.out.println("person Name = " + person.getName());
        System.out.println("File name = " + document.getName());
        System.out.println("File Size = " + document.getSize());
        
        person.setDocument(document);
        Service.save(person);
        return ResponseEntity.ok().build();
    }

Then I have this as my client call:

public abstract class AbstractBaseRestClient {
  public AbstractBaseRestClient() {
    super();
  }
  protected HttpPost buildPostMultipartRequest(String uri) {
    StringBuilder sb = new StringBuilder();
    sb.append(BASE_URL).append(uri);
    HttpPost httpPost = new HttpPost(sb.toString());
    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    //builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
    builder.addTextBody("person", "{name:Justin}", ContentType.APPLICATION_JSON);
    File photo= new File("C:/path/to/logo.png");
    try {
      builder.addBinaryBody("document", new FileInputStream(photo), ContentType.APPLICATION_OCTET_STREAM, photo.getName());
    } catch (IOException e) {
      e.printStackTrace();
    }
    HttpEntity multipart = builder.build();
    httpPost.setEntity(multipart);
    return httpPost;
  }
}

public class Client extends AbstractBaseRestClient {     
  public Client() {     }
  
  public String setImage() { 
    String uri = "/api/v1/upload";       
    int expectedResponseCode = 200;          
    HttpPost httpPost = buildPostMultipartRequest(uri);          
    return makeRestCall(httpPost, expectedResponseCode);     
  } 
}

public class RunTestClient {

    public static void main(String[] args) {
        Client client = new Client();
        String sendImage = client.setImage();
        log(sendImage);
    
    }
    private static void log(String msg) {
        System.out.println(msg);
    }

}

My person object is:

public class Person{

  private String name;
  private MultipartFile document;
  
  
  public Person() {
    super();
  }
  
  public Person(String name) {
        super();
        System.out.println("Name: " + name);
        this.name = name;
  }
  
  public Person(String name, MultipartFile document) {
    super();
    this.name = name;
    this.document = document;
  }
  
  
  @Override
  public String toString() {
    return "Person [name=" + name + ", document=" + document + "]";
  }


  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public MultipartFile getDocument() {
    return document;
  }
  public void setDocument(MultipartFile document) {
    this.document = document;
  }
  
  
}

When running this from the main, I get a 400 error saying:

Incorrect Response Status:: 400. Expected: [200]
The content type is not application/json. It is: text/html; charset=UTF-8

Does anyone see where I am going wrong? Any assistance would be greatly appreciated as I have not been able to figure this out yet. I am not sure why my request is not being accepted.
