This is a recently created wiki, I'm sure it's a configuration problem, resulting in those errors.
ThumbnailRenderJob::hitThumbUrl: invalid thumb URL: /w/thumb_handler.php/3/31/Agustus_28_2017_SK_081_Surat_ajakan_kompetisi_GANESHA.pdf/page1-640px-Agustus_28_2017_SK_081_Surat_ajakan_kompetisi_GANESHA.pdf.jpg
A private wiki can probably live without thumbnail prerendering anyway.

At a glance, it might be that it's expecting a URL and instead it's only getting a path?
Turns out id_internalwikimedia is probably showing up more because it's having a lot of activity, but all private wikis are affected. The prerender job has always failed for them, apparently.
On a public wiki $file->getThumbUrl gives a fully qualified URL:
https://upload.wikimedia.org/wikipedia/commons/thumb/7/7d/%28JFK%2C_April_26%2C_2018_release%29_10_%28JFK%2C_April_26%2C_2018_release%29.pdf/page1-640px-%28JFK%2C_April_26%2C_2018_release%29_10_%28JFK%2C_April_26%2C_2018_release%29.pdf.jpg
On a private wiki, it's just a path:
/w/thumb_handler.php/7/78/2009-10_Wikimedia_Foundation_Annual_Plan_FINAL.pdf/page1-640px-2009-10_Wikimedia_Foundation_Annual_Plan_FINAL.pdf.jpg
Since thumbnail URLs require auth on private wikis, the pre-render job wouldn't work anyway, as the MediaWiki cURL client wouldn't be logged in. It's probably best to skip pre-rendering on private wikis, where it's less important.
