clone_package() error from when add_access_to=NULL

[laurenwalker]

I'm trying to perform a simple script that clones a package from one STAGING member node to another. When I call clone_package(), I get an error that seems to stem from arcticdatautils. This seems confusing since I was under the assumption that arcticdatautils augments/uses the datamgmt library.

I found that the error is stemming from the add_access_to parameter, when it is set to NULL. However the vignette for clone_package() says that NULL is a valid value.

My script

# Copy a data package to another member node!

rMapPid="resource_map_urn:uuid:e9b505ba-086b-4bde-b5a3-e185a25a5004"
from_d1Env="STAGING" 
from_d1Node="mnTestKNB" 
to_d1Env="STAGING"
to_d1Node="mnTestARCTIC"

library(datamgmt)
library(dataone)

options(dataone_test_token = "...")

from=D1Client(from_d1Env, paste("urn:node:",from_d1Node,sep=""))
to=D1Client(to_d1Env, paste("urn:node:",to_d1Node,sep=""))

clone_package(rMapPid, from, to, add_access_to=NULL, change_auth_node=TRUE, public=TRUE, clone_children=TRUE)

Output

Creating a resource map

Error in arcticdatautils::set_access(to@mn, pids = new_resource_map_pid,  : 
  Argument 'subjects' must be character class with non-zero number of characters.

Work-around

When I add at least one subject to the add_access_to parameter, the clone_package() function works:

clone_package(rMapPid, from, to, add_access_to="public", change_auth_node=TRUE, public=TRUE, clone_children=TRUE)

Thanks for the report @laurenwalker - seems like a documentation error more than anything. I think we decided a while back to require adding access to someone though maybe that should be reconsidered
