No Mock Online error

Hi,

I am trying to run some tests on a facebook bot using the docker container mode. I've had no issues with the sample, i've got docker-compose and everything else. I am following the set up provided in the sample. When I try to run my tests, it detects them but they all fail - jasmine times out because of a 'No Mock Online' error (in testmybot/node_modules/botium-core/src/containers/DockerContainer.js:424:16).

I've ran the tests in debug mode for botium and testmybot, here is the no mock online bit:

I am unsure whether this is a configuration problem on my end or not. The facebook webhook port and path that I am giving in the testmybot.json are the ones my fb page is subscribed to, and I am using ngrok to create that tunnel. The app is not published to facebook yet, so only users marked as testers can access it. Other thing to note is that I am making calls to IBM Watson API in the orchestration to process the user inputs. Any help would be much appreciated :)
