identifier causes issue with creating client in zenodo sandbox

[collinschwantes]

metadata <- list (
  title = "New Title",
  abstract = "This is the abstract",
  creator = list(list (name = "A. Person"), list(name = "B. Person")),
  identifier = "10.5072/zenodo.168108"
)

# create a new client with metadata
cli <- depositsClient$new(
  service = "zenodo",
  sandbox = TRUE,
  metadata = metadata
)

returns:

Error in enc2utf8(path) : argument is not a character vector

Interestingly this does not error out if sandbox is FALSE.

Not sure if this is the problem but https://sandbox.zenodo.org/records/168108 returns a 404 error, but https://zenodo.org/records/168108
resolves to a real page.
