I don't know the answer to that, but in this case, I'm pretty sure 
Github Actions couldn't be more helpful, because the error message was 
coming from R in these lines in your Github script:

           install.packages('remotes')
           saveRDS(remotes::dev_package_deps(dependencies = TRUE), 
".github/depends.Rds", version = 2)
           writeLines(sprintf("R-%i.%i", getRversion()$major, 
getRversion()$minor), ".github/R-version")

I have the same lines in my script, so I suspect you copied these from 
another package, as I did.

To diagnose that kind of error, just start a clean R session, set the 
working directory to your package directory, and try to execute them. 
You'll see the same error message as your Github action got.  Then you 
can debug that the way you debug any other R error message:

- Break it up into separate pieces, and discover it happens in 
remotes::dev_package_deps(dependencies = TRUE)

- Run debug(remotes::dev_package_deps), and run just that one command, 
tracing through until you can isolate the issue.
