A page (500 error) displays that states:

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

The program console terminal shows:

It looks like you hit a bug in the earlier version of Rails this was on! Fortunately it was fixed in a later release, and everything seems to be working now.

Update your gems by running bundle install, restart your mock_sensor and rails app server, and you should be set.

Thank you for reporting these issues!
