Hello there! All I can say, from the error in your console, that There might be some syntax or Field error in your Schema. That's why it keeps saying Invalid Schema and won't let you add any entries in Mongo. Also, Deprecation Warning is something that you can ignore if you'd like to. But you're getting deprecation error coz you're using deprecated string parser lib/methods, you might wanna migrate to new URL string parser by mentioning { useNewUrlParser: true }.

Hello,

Not sure if you got this error fixed yet. I added the "{useNewUrlParser: true}" option to the mongoose.connect line and the deprecation error stopped.

// mongodb connection
mongoose.connect('mongodb://localhost:27017/bookworm', {useNewUrlParser:true});
var db = mongoose.connection;
// mongo error
db.on('error', console.error.bind(console, 'connection error:'));

Hope this helps,

Keegan
