Describe the bug
Error in makeSummary: invalid json response body at https://www.google.com/sorry/index?continue=https://www.youtube.com/watch%3FprettyPrint%3Dfalse%26v%3D5A8UUovaSb8%26pbj%3D1&q=EgQDgW_cGKyZ9bEGIjDIbez6kcN4Ofhrrbcfy2T6brx1CtlOvEP6CvOF0rtGbElS0CP3ISqeUAkwFsUF2MgyAXJaAUM reason: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

Until a few days ago, it was working fine, but since 4-5 days ago, this error has been coming up. If you remove youtubei, that error does not appear. However, because I need a transcript, I have to use youtubei, so I am reporting this issue.
my function
const youtube = new Client();
async function makeSummary(req,res){
const { videoId, lang, ask, email } = req.body;
.....
const transcript = await youtube.getVideoTranscript(videoId);
console.log(transcript,'transcript')

}
result
Error in makeSummary: invalid json response body at https://www.google.com/sorry/index?continue=https://www.youtube.com/watch%3FprettyPrint%3Dfalse%26v%3D5A8UUovaSb8%26pbj%3D1&q=EgQDgW_cGKyZ9bEGIjDIbez6kcN4Ofhrrbcfy2T6brx1CtlOvEP6CvOF0rtGbElS0CP3ISqeUAkwFsUF2MgyAXJaAUM reason: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

This works fine on my end

const client = new Client();
const transcript = await client.getVideoTranscript("5A8UUovaSb8");
console.log(transcript);

It seems like your error is caused by YouTube detecting your IP as malicious (can be caused by sending too many requests with the same IP, using a VPN, or other stuff). Unfortunately, there's nothing I can do (of which I'm aware) to work around this.

I'm getting this on all requests now too. I wonder if Google recently deployed something for this.

I'm going to close this since there's not much I can do to solve this issue, however, you can try using OAuth: #113 (comment)
