If you are getting this kind of error using your packages (or others)
Error in curl::curl_escape(names(url$query)) : `url` must be a character vector.
This is caused by changes in
httr v1 that is now on CRAN - it now doesn’t accept an empty list
list() passed to the
query parameter (which we sometimes used as a default if no arguments passed by a user), and throws an error. This is a super easy fix - we’ll get new versions on CRAN as soon as we can.
