send_event error

[cbradford22]

I am trying to setup your application on Ubuntu. Currently my Electron device is sending the events successfully and the Google API is responding with the correct location. The map is not showing any devices available and if I try to test sending data (localhost:8080/send_event) I get the following error:

TypeError: Cannot read property 'send' of undefined

This is the response I get on the webhook:
