I have a OneSignal setup for sending notification to specific users via external user id as follows

$fields = [
    'app_id'                        => env( 'app.onesignalAppKey' ),
    'priority'                      => 10, // High priority.
    'include_external_user_ids'     => [ md5( $contact['email'] ) ],
    'channel_for_external_user_ids' => 'push',
    'headings'                      => [ 'en' => $this->subject ],
    'contents'                      => [ 'en' => $this->message ],
    'url'                           => [ 'en' => base_url( $this->args['log_extra']['url'] ) ]
];

$fields = json_encode($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, env( 'app.Onesignalurl'));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json; charset=utf-8',
    'Authorization: Basic '. env( 'app.onesignalAPI' )));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$response = curl_exec($ch);
curl_close($ch);

While testing I'm receiving notification, but clocking the notification redirect to wrong url.

https://example.com/onesignal/{"en"=>"https://example.com/correct-path"}

OneSignal service worker installed with scope set to /onesignal/

Am I don't something wrong here..?
