Trying to deploy renders this message in the logs, and nothing deployed to the end machine. There is a similar issue for the 6.x version but the only solution offered there is to reinstall everything having to do with deploy, and I've done that once already.
It doesn't matter if I use "Memory Processor" or "Batch processor", the error message is the same. I do however get a progress-bar when using "Batch", something I don't get when using "Memory".
Not really sure if this is a support request or a bug report, or what to do now.
