Looking for a cleaner way to access custom properties, seems like lateinit is not playing well when spring is reading and initialising properties via yaml. I have a class

@ConfigurationProperties("maintenance")
class MaintenanceProperties {
var foo : String ? = null 
}

when we change it to => lateinit var foo : String , kotlin gives us runtime error lateinit property foo has not been initialized
Without lateinit The way I am forced to access it is properties.foo!! ,one way to get rid of !! is to perform a null check but this approch doesn't work well when we have nested properties (we end up with ugly null checks). Is there a better way to get rid of !! and make the application failed during startup if the property is not defined ?
