TypeError: Cannot destructure property 'client_secret' of 'credentials.installed' as it is undefined. showing in my console please help us

Hello,
that error is probably because you are missing credentials.json line 18. save the file credentials.json to your working directory.

hello,
do you know how can I update a file?

Open the credentials.json file and replace the web key to installed

Hi !! Is it possible with your code that each user can use their own google drive account?
