Error: invalid version specification ‘6003’

[JohnCoene]

I keep getting the most curious error message.

In a package, I have the following class.
Note the issue with the constructor.

Counter <- R6::R6Class(
  "Counter",
  public = list(
    x = 0L, 
    # no default value for `x`
    initialize = function(x){
      self$x <- x
    },
    inc = function(){
      self$x <- self$x + 1
    }
  )
)

devtools::load_all()
Counter$new()
 #> Error in initialize(...) : argument "x" is missing, with no default

In my test file

test_that("counter", {
  obj <- Counter$new()
})

This should fail obviously.

#> devtools::test()

I think the issue is broader than this but the above example is one way I found to reproduce it.

r$> sessioninfo::session_info()

Apologies, this does not seem reproducible.
