ERROR (node:7) [DEP0005] DeprecationWarning: Buffer() when using clientCredentialsGrant

[ghitafilali]

I am trying to query the spotifyAPI from an AWS Lambda function and I get an error that prevents me from doing so because of the use of Buffer() in the function clientCredentialsGrant:
ERROR (node:7) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

This is the code that I use to do so (it is for the most part inspired from your examples):

var spotifyAPI = new SpotifyWebApi({
        clientId: "clientId",
        clientSecret: "clientSecret",
    });
    
    spotifyAPI.clientCredentialsGrant().then(
        function (data: any) {
            console.log('The access token expires in ' + data.body['expires_in']);
            console.log('The access token is ' + data.body['access_token']);

            // Save the access token so that it's used in future calls
            spotifyAPI.setAccessToken(data.body['access_token']);
        },
        function (err: any) {
            console.log('Something went wrong when retrieving an access token', err);
        }
    );

Could you please help me fix this issue?

This is an issue that I had with the node spotify web api not with this library
