React native IAP (Android) Validation receive Problem - react-native

Question

I added react-native-iap library( https://github.com/dooboolab/react-native-iap ) for using subscriptions.
Work well on IOS but I have some issues on Android.
On Android side perfectly working subscription person. I need to check expired date for block expired users. For IOS side I use RNIap.validateReceiptIos(receiptBody, false) this give me expired date and expired_ms. I used these but on Android side I use
const result = await RNIap.validateReceiptAndroid(
'com.test.app',
'test_sku_1m_acc',
//below token comes from RNIap.getPurchaseHistory() -> purchaseToken
'faolcmekaiihplkgoaljnfjh.AO-J1OxykzAlHtDtn0-NRHGUBavVbhA_bBLVYPIlc4yUMkHTLXrA_V66lBsZYKknGt-gcCZgznCXKNww0BW9FLuf4ah23HhB_Q',
//below token comes from localhost node.js backend (nodejs Code *)
'ya29.c.Kp0B7QcDz53Bt4YeXHZ6lOjSm7NW9FW0pNwSgX78EQVYNlhSoY2ZM-lhug4mODUy8lzghDuJ8SVj9Lw1Dtvh8ZuB8YFEEv_phTc_YOwJ2PK1_WPyS3nRuF-B96wJADN0F6QBCShHl2uOxEAocNyoCKzb6k1YVPBZxENGS6kwBXfcnNR_Hu4-TKpnl3y0s6vX5_XE_viR46d9cO73cdXIjA',
true, // for subscriptions should pass "true"
).catch((err) => {
console.log('err', JSON.stringify(err));
})
the code returns {"statusCode":401,"line":126336,"column":53,"sourceURL":"http://192.168.2.27:8081/index.bundle?platform=android&dev=true&minify=false"}
This problem is from me or from library. Thank you for your response.
Note: node.js Code *:
const open = require("open");
const { google } = require("googleapis");
const account = require("./service-account.json");
const express = require("express");
const app = express();
const JWTClient = new google.auth.JWT(
account.client_email,
null,
account.private_key,
["https://www.googleapis.com/auth/androidpublisher"]
);
app.get("/", (req, res) => {
JWTClient.getAccessToken((err, token) => {
if (err) {
return res.status(404).send("get access token failed");
}
return res.status(200).send(token);
});
});
app.listen(8000);
open("http://localhost:8000");
