[droidriz]

Hi,
first of all thank you for all the work!
i am trying to run mock bot in local and I have built image from repositry when i run i am getting the following error

restify listening to http://[::]:80 (node:1) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'substr' of undefined at _default (/bot/lib/generateDirectLineToken.js:31:80) at async Immediate.<anonymous> (/bot/lib/index.js:506:7) (Use node --trace-warnings ...to show where the warning was created) (node:1) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag--unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1) (node:1) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

thanks.
