pkgdown::build_favicons(): HTTP 500 Internal Server Error

[lschneiderbauer]

Hi all,

since a couple of weeks I seem to only get a HTTP 500 Internal Server Error in response to
calling pkgdown::build_favicons() from an R package environment.

> pkgdown::build_favicons()
── Building favicons ─────────────────────────────────────────────────────
ℹ Building favicons with <https://realfavicongenerator.net>...
Error in `pkgdown::build_favicons()`:
! API request failed.
Caused by error in `httr2::req_perform()`:
! HTTP 500 Internal Server Error.
Run `rlang::last_trace()` to see where the error occurred.

Best, L

That's not an issue with https://realfavicongenerator.net, I can build locally without issue.

Can you retry after installing the dev version of pkgdown:

# Install development version from GitHub
# install.packages("pak")
pak::pak("r-lib/pkgdown")

[lschneiderbauer]

Interesting.

I have the same issue when using the latest development version.

[lschneiderbauer]

Oh, do I actually need to create an account there to be able to use the service?

[jayhesselberth]

No, you don't need an account. pkgdown uses an API key.

Assuming this was an intermittent internet issue. Closing for now.

Just got the same error and felt like a local solution could be useful, so: https://github.com/ramiromagno/favicon.

@ramiromagno Thanks for putting this together. If we continue to see issues with realfavicon generator, we could incorporate this approach into pkgdown, but would have to take a dependency on magick (which is compiled but otherwise lightweight).

[ramiromagno]

Thanks @jayhesselberth! I would be happy to have next pkgdown version making {favicon} obsolete :)

I can confirm I observe the same error and the suggested alternative would be a nice fix 👍🏼

Same issue here! {favicon} by @ramiromagno saved me — thanks!

Same issue for me as well. I'll also note that build_site() failed for me on first use because it calls build_favicons(). Thus I wasn't able to create a package site at all until I used the favicon package by @ramiromagno.
