Kotlin is not taking "is" as start of json key

Question

I am going through very strange and small issue. I have one data class which I am using for Json parsing. That data class (Json) has one attribute

val isExpired: Boolean

but after response creation its not taking isExpired as key. It's always changing it to expried.

"expired": false

what library are you using to parse the json? – s1m0nw1 Jan 25 '19 at 06:48 — s1m0nw1, Jan 25 '19 at 06:48

Are you using Jackson to do the serialization? If so, then the answer would normally be that you need to annotate the property with @JsonProperty("isExpired"). However in the specific case of Boolean properties it's not quite that, as discussed here. So actually what you need to do here is as follows:

data class MyClass(@get:JsonProperty("isExpired") val isExpired: Boolean)
