I’ve got a simple class in Sveltekit with a method which is performing a GET request. The method is the following:

async getRecordDataByBarcode(url) {

        const response = fetch(url, {
            "Authorization": "Discogs token=XXXXXXXXXXXXXXXX",
            "Content-Type": "application/json",
        })
            .then(response => response.json())
            .then(json => console.log(json))
            .catch(error => console.log(error));
    }

the response I’m getting from this is:

{ message: 'You must authenticate to access this resource.' }

yet when I attempt the same request in a REST client I’m getting back a successful response:

what am i doing wrong?

Yes, I made sure the URLs are the same, I output it on a log message and copied/pasted it on the REST client, the same goes for the token.
