chef-client run fails to sync cookbooks with EOFError: end of file reached

Question

When running a cookbook with chef-client, the run fails with this error: EOFError: end of file reached

I'm fairly new to this, and I don't know what this means. The cookbook is a very simple wrapper around the community cookbook which should be good. https://supermarket.chef.io/cookbooks/powershell

Here's the error again:

Synchronizing Cookbooks:
  - windows (1.37.0)
  - ms_dotnet2 (0.0.0)
  - ms_dotnet45 (0.0.0)
  - powershell (3.1.0)
  - chef_handler (1.1.8)
  - ewe-powershell (0.1.0)

Does this mean there is some EOFError in protocol.rb ? But that's part of the community cookbook, which I thought looked pretty solid.

When chef-client starts up, one of the things it has to do is download the cookbook code it is going to use for the run. This is cached locally to speed future runs, but the first time or when files change etc etc. This exception is saying that it is failing while trying to download the ewe-powershell cookbook from the server. This possibly means it was corrupted during the upload process. A quick first check would be to knife cookbook delete that one and re-upload it. If that fails I would start trying to figure out what file is failing to download. If you turn up Chef's log level (-l debug) you should see which URL it is trying to get, which will tell you which file is failing. With that in hand, try curl'ing it directly from Bookshelf (the service with Chef Server that handles file upload and download).
