Error using as.H2o in R

Getting error when using as.h2o. Anyone have ideas?

library(pacman)
p_load(h2o)
data(iris)
localH2O = h2o.init(ip = 'XXX.XX.XX.XXX', port = XXXXX, strict_version_check = FALSE)
train_hex <-  as.h2o(iris, destination_frame = "train_hex")
|=====================================================| 100%
Error in class(obj) <- "rs.scalar" : attempt to set an attribute on NULL

If I try not to assign it, this is the error.

as.h2o(iris,  destination_frame = "train_hex")

It is probably due to running incompatible versions and/or running a development version (the ".9999" at the end of the version number) on your cluster.

I suggest you un-install, and install the latest R client, following these instructions. Try latest stable-build, then if no luck, try the nightly build. And if still no luck, consider upgrading your cluster to either the latest stable, or latest nightly.
