Spring boot: How to convert a 2 dimensional array of dynamic JavaScript Objects into Kotlin
I am trying to send this JSON object to a Spring boot application in Kotlin.
It is a 2 dimensional array of objects that each contain a key that is a string and a value that is an integer like so:
[
[
{
"-1": 272
},
{
"2": 0
},
{
"apple": -1
},
{
"apple": -1
}...
