I tried to stack 3 models. The first 2 can stack, but adding the last, a cubist, gave me this error: Error in { : task 1 failed - "data.frame_ is unknown.".

Quick update: I tried this again and it worked. I think stacks is blameless. It's the parallel steps that seem to generate the errors, and only sometimes. Perhaps my machine is the problem.
I will indeed close this issue, but I do think {stacks} ought to fail more gracefully here. Related to #105 in that {stacks} fails to point out that a candidate failed to train / had some sort of issue pre-stacking and supplies some other, uninformative error. Will work a change into the next release that gives an eye to erroring informatively in this situation.
