Can't import firewall config into Expedition Project

[bbb1381]

I am trying to import a firewall config into a project. I have added the firewall to devices and pulled in the contents with the API key. I have added the device to the project but when I try to import the config, the "Start" button never turns solid green and nothing happens. I have tried running the following:

sudo apt-get update
sudo apt-get install expedition-beta

Also, I get the following in '/tmp/errors':

I'm not sure where to go from here or if I'm missing something. I ran this exact same process on a different Expedition server without issue.
