[pinterest] Can't download Pinterest subsections: "NotFoundError: Requested section could not be found" 404

[Athari]

Gallery-dl seems to download images from a Pinterest section correctly, but when it recurses into subsections, it seems to fail and request incorrect subsection URLs like https://pinterest.com/username/section/subsection/id:DIGITS instead of https://pinterest.com/username/section/subsection/subsubsection (I assume).

Tried running with my config and with --ignore-config, the result is the same. This setup worked correctly before. I updated to the most recent version (1.26.7), but the problem remains.

Command:

gallery-dl "https://ru.pinterest.com/elvirasaif/%D1%81%D0%BE%D0%B2%D0%B5%D1%82%D1%81%D0%BA%D0%B8%D0%B5-%D0%BE%D1%82%D0%BA%D1%80%D1%8B%D1%82%D0%BA%D0%B8soviet-postcards/"

Temporary workaround I used:

1. Open all section pages you want to download
2. Run [...document.querySelectorAll('.eEj.kVc')].map(a => a.href).join("\n") in console, copy into urls.txt
3. Repeat for every subsection containing its own subsections ("123 Pins 45 sections" text is the cue)
4. Put URLs of all opened tabs with sections into the text file too
5. Run gallery-dl --input-file urls.txt

This instruction will probably break pretty fast because CSS classes are shortened and likely unstable.
