My script for retrieving the playlist is experiencing difficulties in calling upon the "btoa" and "item.slice" methods

Having trouble using the "btoa" method to encode the client id and client secret in base64, which are retrieved from the ".env" file. I've also attempted using the Buffer method but encountered an "invalid form" error with Buffer.

Any assistance would be greatly appreciated.

Please see the complete code below:

Answer №1

You made an error in your coding by using the wrong function for converting Bytes to ASCII. The correct function is btoa, not btao.

Conversely, if you need to convert ASCII back to Bytes, make sure to spell it as atob.
