Hi there!

I'm trying to make an image the cover of a playlist and I keep getting a Bad Request error.
The picture is base64 encoded, a jpeg, I've reduced it to 0.01 of it's original size and the permissions are the ones refered on the spotify api website.
Any ideia on what this error could be?

Here is the full error:
Fatal error: Uncaught SpotifyWebAPI\SpotifyWebAPIException: Bad request. in ...\vendor\jwilsson\spotify-web-api-php\src\Request.php:45 Stack trace: #0 ..\vendor\jwilsson\spotify-web-api-php\src\Request.php(254): SpotifyWebAPI\Request->parseBody(Object(stdClass), 400) #1 ..\vendor\jwilsson\spotify-web-api-php\src\Request.php(126): SpotifyWebAPI\Request->send('PUT', 'https://api.spo...', 'ZGF0YTppbWFnZS9...', Array) #2..\vendor\jwilsson\spotify-web-api-php\src\SpotifyWebAPI.php(76): SpotifyWebAPI\Request->api('PUT', '/v1/playlists/1...', 'ZGF0YTppbWFnZS9...', Array) #3 ...\vendor\jwilsson\spotify-web-api-php\src\SpotifyWebAPI.php(1705): SpotifyWebAPI\SpotifyWebAPI->sendRequest('PUT', '/v1/playlists/1...', 'ZGF0YTppbWFnZS9...') #4 ..\php\createPlaylist.php(23): SpotifyWebAPI\SpotifyWebAPI->updatePlaylistImage('1UJzLOz61XQJV7Z...', 'ZGF0YTppbWFnZS9...') #5 {main} thrown in ..\vendor\jwilsson\spotify-web-api-php\src\Request.php on line 45

Hey!
That's strange. It's working when I try it.

Could you share the code you're using? And have you tried with another playlist and/or image?

Sure! I'll try share the important parts:

I have a form that runs this php code:
$playlistName = $_POST['playlistname']; //creates playlist
$newPlaylist = $api->createPlaylist([
'name' => $playlistName
]);

$songTotal = $_POST['songTotal']; //add songs
for($i = 0; $i < $songTotal; $i++) {
$api->addPlaylistTracks($newPlaylist->id, [
$_POST['songId' . $i]
]);
}

if($_POST['cover'] == 'use') { //define cover
$imageData = base64_encode($_POST['playlistImg']);
$api->updatePlaylistImage($newPlaylist->id, $imageData);
}

Then the image that I want to use is the canvas, converted to jpg:
let canvas = document.getElementById('defaultCanvas0');
let img = new Image(200, 200);
img.src = canvas.toDataURL('image/jpeg', 0.01); //this defines the format and the quality
document.querySelector('.preview').appendChild(img);

Since this all happens in a pop up, I'm creating the input with the image data:
let playlistImg = document.createElement('input');
playlistImg.setAttribute('type', 'hidden');
playlistImg.setAttribute('name', 'playlistImg');
playlistImg.setAttribute('value', img.src);

document.querySelector('.create-playlist form').appendChild(playlistImg);

I've checked if the base64 encoding is right, and it seems to be.
Thank you for the quick response
