Hello! Those are typical warnings from node, but I don't know that they should affect the application running. What steps have you tried?

Yes, you are missing environment variables. As this was created for a workshop 3 years ago, there was an accompanying series of steps, including configuring a token to use Rhino Compute and a database. I am unfortunately not able to provide the workshop contents, but the error is pretty self explanatory - you need an environment variable for the application to validate the API calls from the client to the server that you are running. Anything you'll find after process.env. in all capitals will be a environment variable you require.

PORT: the port you want to run on RHINOCOMPUTE_TOKEN: token you get from signing on to rhino compute, which you would need to get separately SESSION_SECRET: a series of characters to authenticate from server to browser DATABASE_URI: a URI to a database that you've set up
