Recently, I upgraded my R version from 3.6.0 to 4.0.0. Since then, I've been encountering the following error during simple GET or POST calls, which I never experienced with the older version. I also upgraded my httr package from version 1.4.1 to 1.4.7:

Error in curl::handle_setopt(handle, .list = req$options) : length(keys) == length(values) is not TRUE

 res <- GET("http://google.com")

curl_options() is NULL.
I am not sure this is causing the issue.
