Estou com esse erro ao tentar fazer o primeiro teste do penúltimo vídeo da série [YouTube API: tutorial para upload de vídeos (OAuth2)]

Então estou com o mesmo problema, você conseguiu resolver?

Assim que conseguir volto com a solução.

Achei uma solução pra mim que funcionou e gostaria de compartilhar:

Em robots/youtube.js
Na linha : 41

async function createOAuthClient() {
const credentials = require('../credentials/google-youtube.json')

  const OAuthClient = new OAuth2(
    credentials.web.client_id,
    credentials.web.client_secret,
    //credentials.web.redirect_uris[0]
    credentials.web.redirect_uris["http://localhost:5000/oauth2callback"]
  )

  return OAuthClient
}

function requestUserConsent(OAuthClient) {
  const consentUrl = OAuthClient.generateAuthUrl({
    access_type: 'offline',
    scope: ['https://www.googleapis.com/auth/youtube']
  })

 //Alterei esse log no console para mostrar o link completo com o callback
  console.log(`> [youtube-robot] Por favor, de seu consentimento: ${consentUrl}`+`http://localhost:5000/oauth2callback`)
}

Pra mim funcionou. Diga aí se funcionou pra você.
