To solve the "error is Error: failed to connect to [undefined:27017]", needs to pass the valid path URL of mongo database. In another case, you can replace it with the localy installed mongo database. Replace the mongoose connection URL with:
mongoose.connect('mongodb://localhost/databasename');
It work for me.
