Redirect deleted jobs?

Almost anything is possible, depending on how much customization you’re willing to do. Assisting with customization is outside of the scope of the support that we can offer, per our Support Policy. If you need extra help, you can search for development help in a variety of places — here are a few to start:

Can anyone help me figure this one out? I am a total novice but I tried something like this:

function redirect_deleted_posts() {
global $post;
if (is_single() && $post->post_status !== 'publish') {
wp_redirect(home_url('/lediga-jobb/'));
exit();
}
}

However that broke my website, so something is missing/not correct. Anyone with some idea what might be wrong?

Also I understand perhaps I should try to add the apply_filters( ‘wp_redirect_status’, int $status, string $location ) instead of the post_status publish?
