How to replace this if statement with Alvis Operator?

if (element == null) {
    return null
}
val validationObject = element.asJsonObject
val validation: MutableMap<String, String> = HashMap()
for (entry: Map.Entry<String, JsonElement> in validationObject.entrySet()) {
    val key: String = entry.key
    val value: String = entry.value.asString
    validation.put(key, value)
}

?: (`e`lvis operator) gives you either a default value or default behaviour
https://kotlinlang.org/docs/reference/null-safety.html#elvis-operator

The only thing I can see from your snippet that can be null is element

val validationObject = element?.asJsonObject ?: JsonObject()
val validation: MutableMap<String, String> = HashMap()
for (entry: Map.Entry<String, JsonElement> in validationObject.entrySet()) {
    val key: String = entry.key
    val value: String = entry.value.asString
    validation.put(key, value)
}

if you don't want the code below do an 'empty run' you can also just do something like:

val validationObject = element?.asJsonObject ?: return if your function doesn't return any value
