HarmonyOS 鸿蒙Next 华为登录成功，但是authAccountTask.getResult()返回的token一直为null

Task<AuthAccount> authAccountTask = AccountAuthManager.parseAuthResultFromIntent(data);
if (authAccountTask.isSuccessful()) {
    AuthAccount authAccount = authAccountTask.getResult();
    Log.e(TAG, "authAccount is " + authAccount);
    Log.e(TAG, “getAuthorizationCode:” + authAccount.getAuthorizationCode());
    Log.e(TAG, “getIdToken:” + authAccount.getIdToken());
    Log.e(TAG, "name is " + authAccount.getDisplayName());
    Log.e(TAG, "token is " + authAccount.getAccessToken());
} else {
    Log.i(TAG, "signIn failed: " + ((ApiException) authAccountTask.getException()).getStatusCode());
}
