Drive download returning token JSON object
Problem
Hello, I'm having a problem downloading from the Drive using this API (v3). The data returned from the API is of the form: [code block] My code is roughly as follows (parts ommited due to confidentiality reasons): [code block] auth is an object created using a derivation of this example: https://developers.google.com/drive/v3/web/quickstart/nodejs#step_3_set_up_the_sample Am I doing something wrong, or has the API changed somehow?

Update API Call to Handle Token Response Properly
The issue arises because the API response is returning a token JSON object instead of the expected file data. This can occur if the API call is not correctly formatted or if the authorization token is not being used properly, leading to an authentication error that results in a token response instead of the desired file download.

Verify API Endpoint and Parameters
Ensure that the API endpoint you are calling is correct and that all required parameters are included. The endpoint for downloading files should be formatted as follows: `https://www.googleapis.com/drive/v3/files/{fileId}?alt=media`. Replace `{fileId}` with the actual ID of the file you wish to download.
javascriptconst fileId = 'your_file_id_here'; const url = `https://www.googleapis.com/drive/v3/files/${fileId}?alt=media`; - 2
Ensure Proper Authorization
Check that your authorization token is valid and has the necessary scopes to access the file. The required scope for downloading files is `https://www.googleapis.com/auth/drive.readonly`. If the token is expired or does not have the right permissions, refresh or regenerate the token.
javascriptconst {google} = require('googleapis'); const drive = google.drive({ version: 'v3', auth }); - 3
Handle API Response Correctly
Make sure to handle the API response properly. If the response is a token JSON object, log the response to understand why it is being returned. This will help in debugging the issue further.
javascriptdrive.files.get({ fileId, alt: 'media' }, { responseType: 'stream' }) .then(response => { response.data.on('end', () => { console.log('Download completed'); }) .on('error', err => { console.error('Error downloading file:', err); }); }) .catch(error => { console.error('API Error:', error); }); - 4
Check for API Changes
Review the Google Drive API documentation for any recent changes that might affect your implementation. Ensure that your code aligns with the latest API specifications.
Validation
To confirm the fix worked, attempt to download the file again using the updated code. You should receive the file data instead of a token JSON object. Additionally, check the console for any error messages that may indicate further issues.
