I'm running batch convert to pdf but always get following error:

                             ^  ->  pdf  [--------------------------------------------------] 0%  Starting...

Node version: v8.1.3

What could the issue be?

Might be related to cloudconvert/cloudconvert-node#14
Can you try if it is resolved after updating using npm install -g cloudconvert-cli?
