自分自身と同じ問題に遭遇した他の人は見かけませんでした。私はAPIを使って小惑星のリストを取得し、小惑星を追加して取得することができるアプリエンジンを持っています。今度は、新しい小惑星を追加するときに計算エンジンのインスタンスを開始して、計算を行い、アプリエンジンに返答を送り返したいと思います。App EngineがCompute Engineインスタンスを開始します - IllegalAccessError
今私が持っている：
String projectID = "better-world-175517";
String zone = "us-east1-c";
Compute computeService = createComputeService();
Compute.Instances.List request = computeService.instances().list(projectID, zone);
InstanceList listResponse;
listResponse = request.execute();
for(Instance instance : listResponse.getItems())
{
System.out.println(instance);
}
と、この私のcreateComputeServiceである（）メソッド：
public static Compute createComputeService() throws IOException, GeneralSecurityException {
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
GoogleCredential credential = GoogleCredential.getApplicationDefault();
if (credential.createScopedRequired()) {
credential =
credential.createScoped(Arrays.asList("https://www.googleapis.com/auth/cloud-platform"));
}
return new Compute.Builder(httpTransport, jsonFactory, credential)
.setApplicationName("test_BetterWorld/1.0")
.build();
}
をしかし、私は、私は取得しています。このエラーログを把握することができていない、それがあります多くの情報を提供していない：

私はこの問題は、「request.execute（）」である知っているが、私はよこれを修正する方法が不明です。必要に応じてコードのスニペットを投稿することができます。私はそれが可能であることを知っている、ちょうど私がcomputeServiceまたは何かを使用すべきではないと思う。
ご協力いただきありがとうございます。
