I get this error message from Pulumi:

error: rpc error: code = InvalidArgument desc = required configuration keys were missing

Is there a way to get Pulumi to provide a little more information, such as which keys were missing? Or at the very least, which keys were present, and then maybe I can figure out which keys were missing if I know which ones were present. I've tried debugging at level 20, and I still can't get more information about this particular error.
