How does the tor user agent change? resolved - node.js

Question

I use node.js to make requests on google.
I used puppeteer but he detected my robot.
so i used tor-request.
I can change my ip at each connection.
But google still hangs with the same error message.
I want to change the user-agent of the tor-expert bundle.
How to do ?
Our systems have detected unusual traffic from your computer network.
Please try your request again later. Why did this happen?
IP address: 109.70.100.** Time: 2019-08-03T08:47:17Z URL:

var tr = require('tor-request');
tr.TorControlPort.password = "***";
io.sockets.on('connection', async(socket) => {
socket.on('key', function(value) {
function torIp() {
tr.request('https://www.google.com/search?q=re&gbv=1&sei=6UlFXY6mKsSiab3EjbAF', function(error, response, body) {
if (!error && response.statusCode == 200) {
console.log("Your public IP is: " + body);
}
socket.emit('google_web', body)
});
}
torIp();
tr.renewTorSession(function(error, msg) {
console.log(error);
console.log(msg);
if (msg) {
torIp();
}
});
})
})

To change the user agent, you can use the method described here, a tor-request issue:
tr.request({
url: 'https://www.google.com/search?q=re&gbv=1&sei=6UlFXY6mKsSiab3EjbAF',
headers: {
'user-agent': 'giraffe'
}
}, function(error, response, body) {
// ...
});
Just replace giraffe with whichever user agent you wish.
(But, as the comment noted, Google may well have blocked certain Tor exit nodes completely, in which case changing the user-agent won't help)
