Unexpected error refreshing access token

Google Cloud Compute Infrastructure
1

hello, I am a student who is currently designing an application by integrating the Google API. I’m currently putting together a test API call and token request. However, I experienced problems when requesting a token. The problem I experienced was: java.io.IOException: Unexpected error refreshing access token. The following is an attachment to my code and error

Code:

package com.example.coba;

import com.google.auth.oauth2.GoogleCredentials;
import com.google.auth.oauth2.ServiceAccountCredentials;
import java.io.FileInputStream;
import java.util.Collections;

public class MainActivity {
    public static void main(String[] args) {
        try {
            // Load the service account key JSON file
            FileInputStream serviceAccount = new FileInputStream("D:\\SEMENTARA\\ta-yoga-418816-bf5d93710c8d.json");

            // Authenticate a GoogleCredential with the service account
            GoogleCredentials credential = ServiceAccountCredentials.fromStream(serviceAccount)
                    .createScoped(Collections.singleton("https://script.googleapis.com/v1/scripts/AKfycbwyHyH2Fp_7E6mR9tomsywXGd83-w59NFx5KHPiCv-_PgHXhpwn_8xFiKi2VRbHGmiv:run?"));

            // Use the GoogleCredential to create an authorized HttpTransport
            credential.refreshIfExpired();
            String accessToken = credential.getAccessToken().getTokenValue();

            // Now you can use the access token to authenticate your requests
            System.out.println("Access Token: " + accessToken);
        } catch (Exception e) {
            e.printStackTrace();
            if (e instanceof java.io.IOException) {
                System.out.println("An IOException occurred. This may be due to a problem with the network connection, or the file system.");
            } else if (e instanceof IllegalStateException) {
                System.out.println("An IllegalStateException occurred. This may be due to an error in the program logic.");
            } else {
                System.out.println("An unexpected error occurred: " + e.getMessage());
            }
        }
    }
}

error:
