After I click the Sign Up button I get 'data and salt arguments required' in the browser.

Any ideas why?

Without seeing your code it's hard to validate, but I ran into the same error. I used an arrow function, which "this" didn't work correctly with. If you're using an arrow function like UserSchema.pre('save', (next) => { update it to a regular function like UserSchema.pre('save', function(next) { and see if that fixes it for you.
