[REGRESSION] A large number of images are missing in the most recent Wikipedias

[Inbefortus]

• ZIM

Examples:

• https://library.kiwix.org/viewer#wikipedia_en_top_maxi_2023-02/A/Centromere
  

• https://library.kiwix.org/viewer#wikipedia_en_top_maxi_2023-02/A/Carillon
  

• https://library.kiwix.org/viewer#wikipedia_en_top_maxi_2023-02/A/Guangxu_Emperor
  

Upstream is fine:

• https://en.wikipedia.org/api/rest_v1/page/html/Guangxu_Emperor

• https://en.wikipedia.org/api/rest_v1/page/html/Carillon

• https://en.wikipedia.org/api/rest_v1/page/html/Centromere

This month's zimcheck output is significantly longer than last month's:

French Wikipedia appears to be affected as well:

• https://library.kiwix.org/viewer#wikipedia_fr_all_maxi_2023-02/A/L%C3%A9onard_de_Vinci

• https://library.kiwix.org/viewer#wikipedia_fr_all_maxi_2023-02/A/Jacques-Louis_David
  

Could all this be related to the new approach in response to 429 errors? I sincerely hope not, because the new strategy makes a significant difference!

@uriesk I guess we have built a regression here... This confirms my first impression... but I don't have run any investigation so far.

Good news is that missing images are in the ZIM but, for example https://library.kiwix.org/content/wikipedia_en_top_maxi_2023-02/I/Chromosome.svg.png, but https://library.kiwix.org/content/wikipedia_en_top_maxi_2023-02/I/Chromosome.svg.png.webp is referenced.

This makes sense, as I was perplexed as to why the ZIM with so many "missing" images still remained larger than the previous one... This clarifies it. I'm relieved to hear it's not as severe!

Confirmed, just removing the webp ending in dev tools allows the image to be loaded. Rather strange error, in particular that it has happened in some cases, but not in the vast majority of cases.

@kelson42 Your fix was effective 👍
