I’ve been observing several times with the “Continue Generating” option in ChatGPT plus interface. The text stream is not ordered sometimes, and the stream do not start from where it ended. Output streams as if it’s generating an entirely new response every time i click the “Continue Generating” option, in case if the response is large.
This problem has been observed in API too. I’m attaching the ChatGPT response during my conversation to a question. *Observe that the code repeats itself at the points where I chose “continue generating” option
Question: “but i can’t do this everytime an error occurs, isn’t it?”
Response:
“”"
You’re correct; manually deleting the token_files directory each time an error occurs is not a sustainable solution. Instead, you should handle token-related errors more gracefully within your code. Here are a few strategies to consider:
Strategies for Managing OAuth2 Tokens
-
Token Expiry Handling:
- Automatically refresh the token when it expires.
-
Improved Error Handling:
- Add robust error handling to manage specific OAuth2 errors.
-
Token Storage and Management:
- Store and manage tokens securely and ensure they are up-to-date.
Token Refresh Handling
Make sure your code handles token expiration and refreshes the token when necessary. Here’s an updated version of your authorize function to include token refreshing:
google_async.js
const { google } = require('googleapis');
const fs = require('fs').promises;
const path = require('path');
const express = require('express');
const destroyer = require('server-destroy');
async function openURL(url) {
const open = (await import('open')).default;
open(url);
}
async function ensureDirectoryExists(workingDir, tokenDir) {
try {
await fs.mkdir(path.resolve(workingDir, tokenDir), { recursive: true });
console.log("Token directory created successfully");
} catch (err) {
console.error('Failed to create directory:', err);
}
}
async function authorize(API_SERVICE_NAME, API_VERSION, scopes, prefix = '') {
const workingDir = process.cwd();
const tokenDir = 'token_files';
const tokenFileName = `token_${API_SERVICE_NAME}_${API_VERSION}${prefix}.json`;
const tokenFilePath = path.resolve(workingDir, tokenDir, tokenFileName);
const credentialsFilePath = path.resolve(workingDir, 'credentials2.json');
console.log(`Credentials file location: ${credentialsFilePath}`);
await ensureDirectoryExists(workingDir, tokenDir);
const credentials = JSON.parse(await fs.readFile(credentialsFilePath, 'utf8'));
const { client_secret, client_id, redirect_uris } = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(client_id, client_secret, redirect_uris[0]);
try {
const token = JSON.parse(await fs.readFile(tokenFilePath, 'utf8'));
oAuth2Client.setCredentials(token);
if (token.expiry_date <= Date.now()) {
console.log('Token expired, refreshing...');
const newToken = await oAuth2Client.refreshAccessToken();
oAuth2Client.setCredentials(newToken.credentials);
await fs.writeFile(tokenFilePath, JSON.stringify(newToken.credentials));
}
await oAuth2Client.getAccessToken();
} catch (error) {
if (error.code === 'ENOENT') {
return getNewToken(oAuth2Client, tokenFilePath, scopes);
} else {
throw error;
}
}
return oAuth2Client;
}
async function getNewToken(oAuth2Client, tokenFilePath, scopes) {
const app = express();
const server = app.listen(9999, () => {
openURL(oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: scopes,
prompt: 'consent',
redirect_uri: 'http://localhost:9999/oauth2callback'
}));
console.log('Server listening on port 9999 - follow the URL to authenticate.');
});
destroyer(server);
return new Promise((resolve, reject) => {
app.get('/oauth2callback', async (req, res) => {
const { code } = req.query;
if (!code) {
res.status(400).send('Failed to get the code from Google');
server.destroy();
return reject(new Error('No code provided by Google'));
}
try {
const { tokens } = await oAuth2Client.getToken(code);
oAuth2Client.setCredentials(tokens);
await fs.writeFile(tokenFilePath, JSON.stringify(tokens));
res.send('Authentication successful! Please close this window.');
resolve(oAuth2Client);
} catch (error) {
console.error('Error while trying to retrieve access token:', error);
res.status(500).send('Authentication failed');
reject(error);
} finally {

}
});
});
}
module.exports = { authorize };
Error Handling in gmail.js
Ensure that gmail.js handles errors gracefully, providing meaningful messages and taking appropriate actions.

Summary
- Token Expiry Handling: Automatically refresh the token when it expires to avoid manual deletions.
- Improved Error Handling: Add robust error handling to manage specific OAuth2 errors.
- Proper Token Management: Ensure tokens are stored securely and managed efficiently.
By implementing these strategies
<*******Chose the option of “continue generating”********>
Great to hear that your script worked after deleting the token_files directory! However, as you pointed out, manually deleting the directory every time an error occurs is not a practical solution. To manage tokens more effectively and ensure your application handles errors gracefully, you should implement better token management and error handling strategies.
