404 not found exception on GetSimilarArtists

[Offbeatmammal]

just wondering if something has changed in the SpotifyAPI? this code was working on Friday, but today I'm getting an exception:

require_once 'vendor/autoload.php';
$session = new SpotifyWebAPI\Session('?????','?????');
$session->requestCredentialsToken();
$accessToken = $session->getAccessToken();
$api = new SpotifyWebAPI\SpotifyWebAPI();
$api->setAccessToken($accessToken);
....
$artist = "6eUKZXaKkcviH0Ku9w2n3V";    // Should be Ed Sheeran
$artists = $api->getArtistRelatedArtists($artist);

this now throws:

Uncaught SpotifyWebAPI\SpotifyWebAPIException: Not Found in C:\...\vendor\jwilsson\spotify-web-api-php\src\Request.php:46
Stack trace: #0 C:\...\vendor\jwilsson\spotify-web-api-php\src\Request.php(250): SpotifyWebAPI\Request->handleResponseError('{"error": {"sta...', 404)

other calls, eg $results = $api->search(str_replace(" ","+","Ed Sheeran"), 'artist'); are still working fine

Hello!
I'm afraid this sounds like you've been affected by the recent changes made by Spotify to certain APIs, including "get related artists" 😕

ugh, that sucks. this is a pre-existing app, but I guess Spotify don't really care. thanks for pointing that out, guess we'll just deprecate Spotify support in favour of Last.FM relatedArtists
