Картинка кодируемая в base64 в андройде не декодируется в php base64_decode

Я кодирую на стороне клbента Bitmap в base64

    public String toBase64FromBitmap(Bitmap bitmap){
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 65, byteArrayOutputStream);
    byte[] byteArray = byteArrayOutputStream .toByteArray();

    String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
    return encoded;
}

Затем данные отправляю на сервер

$request = $_GET;


if (isset($request['base64'])) {
    $fileTmpPath = imagecreatefromstring(base64_decode($request['base64']));
 

и получаю ошибку
