[Playwright/Container] problem to generate a PDF / button

[boddedo]

Hello !
It's been a while ! :)
How have you been since then ?

I have a problem to generate PDF using ReadTheDocs CI. (It's a problem I have since multiple month).
EDIT: I finally obtained the status "Build Completed" but impossible to generate a PDF IDK why...

I also finally managed to get myself a 3-month subscription to ReadTheDocs CI and have access to the documentation generation
tell me if you want have an access to it to do some test, and maybe improve your documentation.

Here's my .readthedocs.yaml file :

Do all the pages you want exported have pdf: true in the frontmatter?
The explicit: true option makes all pages excluded for export by default.
