Assign value to roam object

[FinYang]

library(roam)
bee <- new_roam(
  "roam", "bee", 
  function(version) 
    read.csv(
      "https://raw.githubusercontent.com/finyang/roam/master/demo/bee_colonies.csv"))

roam_activate(bee)
bee <- 1

Before installation:

Error in obtainer(roam_flag$version, ...) : unused argument (1)

After installation, no assignment but also no error.

Also can't reproduce with reprex
