Last gggenomes example failed with mysterious error

After reading the second file apparently successful, it just says "Error:" but without any error message...

This is strange. I don't know why this happens. When I build locally it works (with some warnings). Not sure if warnings are treated as errors in this context but I don't think so.

It seems to be an issue with read_gff. Same happens here https://thackl.github.io/gggenomes/reference/read_tracks.html. There are no warnings, though, from read_gff on local builds. The read_paf warnings are unrelated, I think.

Why read_gff fails on CI build, I don't have a clue...

Okay, looking into it a bit more. Debugging GitHub actions is not straightforward. This looks promising but does not work because I get denied errors from rstudio cdn: https://github.com/nektos/act
This also might be an idea but is rather hacky: https://dev.to/retyui/how-debugging-github-actions-with-ssh-273n
So my suggestion would be to upgrade R in the action from 4.0.0 to 4.0.4 to see if some bug that has since been fixed causes this error.

Sound like a good plan to me.

Actual problem is a bug in across() dplyr-1.0.4 tidyverse/dplyr#5765. dplyr-1.0.4-dev works. Fixed dplyr-1.0.5 about to be released.
