Whitelabel Error Page This application has no explicit mapping for /error

Question

I have problem with my application. I added uploading image page but i get problem.

Before my project work corretly. I can login in test1 be user and test3. Admin can log test2 and test3, but when i add uploadImage and i wanna log be Admin i get whitelabel, if i change this for user i get this same problem. I think this should be problem with mapping or scaning, my structure maybe is not correctly but idk because i dont have enough experience. Lower i add my code, if someone need more code, ask.

My uploadImage:

package com.example.imageUploader.gui;

import com.vaadin.flow.component.button.Button;
import com.vaadin.flow.component.orderedlayout.VerticalLayout;
import com.vaadin.flow.component.textfield.TextField;
import com.vaadin.flow.router.Route;
import org.springframework.beans.factory.annotation.Autowired;
import com.example.imageUploader.ImageUploader;
import org.springframework.web.bind.annotation.GetMapping;

import java.awt.*;
// problem moze byc z mapowaniem albo zaleznosciami miedzy folderami ze ten jest za wysoko

@Route("uploadImage")
public class UploadGui extends VerticalLayout
{

    private ImageUploader imageUploader;

    @Autowired
    public UploadGui(ImageUploader imageUploader)
    {
        this.imageUploader = imageUploader;

        TextField textField = new TextField();
        Button button = new Button("upload");
        button.addClickListener(clickEvent -> imageUploader.uploadFile(textField.getValue()));

        add(textField);
        add(button);
    }
}

My run:

package com.example.imageUploader;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Component;

@SpringBootApplication
//@ComponentScan(basePackages = "com.example.imageUploader.gui.UploadGui")
public class ImageUploaderApplication {

    public static void main(String[] args) {
        SpringApplication.run(ImageUploaderApplication.class, args);
    }

}

        appUserRepo.save(appUserUser);
        appUserRepo.save(appUserAdmin);
    }
