generate-recipe fails for CRAN's rstanarm

[andystopia]

rattler-build generate-recipe cran -w rstanarm provides:

Generating R recipe for rstanarm
Error:   × error decoding response body
  ╰─▶ missing field `Title` at line 45 column 1

If I have done my homework correctly, it seems like this repository queries the following URL: https://cran.r-universe.dev/api/packages/rstanarm. The response also doesn't provide dependencies, like a working package would, at a first glance. As of today that response JSON right now is provided at the bottom of this issue. It does list key _type as "failure".

This, admittedly does appear to be an upstream issue with whatever is generating info for r-universe. I can't figure out why this is, (I gave up after 8000 lines of warnings in CI).

Is there a way to generate a recipe straight from the DESCRIPTION file (which seems to have a Title field), without proxying through r-universe?

Hi @andystopia - you could try grayskull and the automatic recipe conversion tool to see if that gives you a good starting point for this recipe :)
