Does anybody have an idea why?

Hi, am getting the same error. I assume something has changed in the way Spotify and/or YT handle the API requests of the script? Hopefully, someone from the development team will see this. They will probably know what could be causing this.

Hi, after some investigation on the code, i found 3 problems:

1. The autentication with oAuth (option 2 of setup) does not work, you must do the autentication with the Browser method (option 3 of setup)
2. Youtube has a max of request by day, so if you try to do too much request even if they are bad, in some point youtube is gonna block you. You need to verify your account with a photo of yourself or an valid id
3. The max number of songs in a youtube playlist is 5000 so if you are tyring to transfer a playlist with more than 5000 songs you obtain a bad request
