Litmus "applications" in config.json

I am attempting to send my newly built email to Litmus via npm run litmus. All seems to go well until the Litmus part which outputs:

[16:53:40] Starting 'litmus'...

Error

Not sure why the applications list is not correct. I have checked them against xml at https://litmus.com/emails/clients.xml

In my config.json I have the applications listed as:
“applications”: ["ol2003","ol2007","ol2010","ol2011","ol2013","chromegmailnew","chromeyahoo","appmail9","iphone5s","ipad","android4","androidgmailapp"]

Any help would be greatly appreciated.
