Using $this when not in object context error on Laravel bootstrap pagination when using Octane

Question

I have setup Laravel Octane on my server with Roadrunner. Everything works fine, except for occasionally pages that use paginator throws

Using $this when not in object context

error. When I restart my octane server, the issue goes away for a certain time, only to reappear.

Here's a snippet of that error

And this is what my controller method looks like

$news = News::filter($filters)
            ->with(['tags', 'categories', 'createdBy'])
            ->where('status', 1)
            ->orderByDesc('publish_date')
            ->paginate(10)
        ;
return view('admin.news.index', compact('news'));

I tried clearing my cache, but still the issue persists. I don't understand what's causing this issue. Any help will be appreciated.
