Facebook login with android sdk not working

Question

I have integrated Facebook login to my android application. It used to work. But now it's not working. When I debugged the application I found that now LoginManager Callback is giving an Exception. I don't know what this is, and how to solve it. And this is the exception I got

exception: "SERVER_ERROR [code] 1675030 [message]: Error performing query. [extra]: Errors while executing operation "ProxyAuthAppLoginStartQuery": At Query.proxy_auth_app_login_start: Failed to resolve field."

code

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.fragment_sign_in, null);
    CardView mSignInFbButton = (CardView) view.findViewById(R.id.sign_up_fb);
    mSignInFbButton.setOnClickListener(v ->{
                if (AccessToken.getCurrentAccessToken() != null) {
                    LoginManager.getInstance().logOut();
                }
                LoginManager.getInstance().logInWithReadPermissions(SignInFragment.this, Arrays.asList("public_profile", "email"));
            }
    );
    callbackManager = CallbackManager.Factory.create();
    LoginManager.getInstance().registerCallback(callbackManager, mFBSignInCallback);
    return view;
}

private FacebookCallback mFBSignInCallback = new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        Beco.getApp().currentUser().signInFacebook();
    }

    @Override
    public void onCancel() {
        Log.d(TAG, "onCancel");
    }

    @Override
    public void onError(FacebookException exception) {
        Log.d(TAG, "onError");
    }
};
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    callbackManager.onActivityResult(requestCode, resultCode, data);

}  

In the LoginManager Callback it's going to public void onError(FacebookException exception) All suggestions are appreciated. Thanks!

Open your registered app in Facebook developer console.

This method will make app publicly available for all testing devices:

1. Select 'App Review' option
2. Make Social Adds public? enable it to 'Yes'

OR

This method will let you test app on selected devices:

1. Select 'Role' option
2. Add 'Testers' for application
