BootStrap.groovy causing grails to fail - grails

Question

migrating old 2.2.2 app to 3.1.2, can i know why this app is crashing because of bootstrap.groovy
any help will be appreciated thank you
using: grails 3.1.2, mysql workbench 6
This is the Bootstrap.groovy to which causes the whole application to stop running
import grailsapp.Location;
import grailsapp.State;
import grailsapp.User;
import grailsapp.Type;
class BootStrap {
def init = { servletContext ->
new State(state: "Issuable", updates: [:]).save(failOnError:true)
new State(state: "Holding", updates: [:]).save(failOnError:true)
new State(state: "In for repair", updates: [:]).save(failOnError:true)
new Location(location: "L163", specific: "Rack 3A", updates: [:]).save(failOnError:true)
new Location(location: "L163", specific: "Rack 3B", updates: [:]).save(failOnError:true)
new Location(location: "L163", specific: "Rack 3C", updates: [:]).save(failOnError:true)
new User(username:"blah", password: User.hashPassword("password"), firstName:"blah", lastName:"blah", isAdmin:true, updates:[:]).save(failOnError:true)
new Type(type:"Dell E6500").save(failOnError:true)
new Type(type:"Dell E6510").save(failOnError:true)
new Type(type:"Dell E6520").save(failOnError:true)
}
def destroy = {
}
}
These are the errors in which it causes

Answer 1

After seeing your State Class, I have checked that 'updates' field is a hasMany relationship. It says that the relation is from 0 to many objects. I mean, It is not obligatory to specify the updates, so if you write your state class without updates, it must be valid:
new State(state: "Issuable")
new State(state: "Holding")
new State(state: "In for repair")
Your problem now is that if you try:
new State(state: "Issuable", updates: [:]).save(failOnError:true) or
new State(state: "Issuable", updates: []).save(failOnError:true)
you'll get an error because updates musn't be a map or a list. It must be an object of 'Update' class.

Answer 2

It looks like the updates field on State is a Set but you're initializing it with a Map. Try:
new State(state: "Issuable", updates: []).save(failOnError:true)
new State(state: "Holding", updates: []).save(failOnError:true)
new State(state: "In for repair", updates: []).save(failOnError:true)
