Devtools fais with cryptic error message

[Unaimend]

Hi, I most definitely made an error during package construction but since devtools fails with a non-helpful error I thought I'd just make an issue:

The following code fails. Maybe there is some way of making the error message more helpful and just to make sure I DO NOT request help with my package here :). Thanks for reading.

(ins)> install_github("Unaimend/cpdBoy", subdir="r_package")
Downloading GitHub repo Unaimend/cpdBoy@HEAD
Error in if (is.na(res)) { : argument is of length zero

(ins)> install_github("https://github.com/Unaimend/cpdBoy/tree/r_package", subdir="r_package")
Downloading GitHub repo Unaimend/cpdBoy@r_package
Error in if (is.na(res)) { : argument is of length zero

To reproduce by yourself:
Follow this tutorial: https://ourcodingclub.github.io/tutorials/writing-r-package/ and do not execute roxygenize()
