Why am I getting org.json.JSONException: Not a primitive array? - arrays

Question

I have this function:
fun getFeed(token: String): Result<Array<Post?>, Exception> {
if (token != "") {
val (request, response, result) = "https://alles.cx/api/feed"
.httpGet()
.header("Authorization", token.toString())
.response()
when (result) {
is Result.Success -> {
println("Result success")
try {
val responseJSON = JSONObject(String(response.data))
if (!responseJSON.has("err")) {
println("Has no error")
var feedArray = arrayOfNulls<Post>(0)
println("HERE?")
var feed = JSONArray(responseJSON["feed"]) // <-----ERROR HERE
println("not here")
println("Made to the for")
for (i in 0 until feed.length()) {
println("For $i")
val jsonObject = feed.getJSONObject(i)
var imageURL: URL? = null
if (jsonObject.has("image")) {
imageURL = URL(jsonObject["image"].toString())
}
feedArray[i] = Post(
jsonObject.getString("id"),
User(jsonObject.getJSONObject("author").getString("id"), jsonObject.getJSONObject("author").getString("username"), jsonObject.getJSONObject("author").getString("name")),
jsonObject.getString("createdAt"),
jsonObject.getInt("replyCount"),
jsonObject.getInt("score"),
jsonObject.getString("content"),
null,
imageURL,
jsonObject.getInt("vote")
)
println("Added post $i")
}
println(feedArray)
return Result.Success(feedArray)
}
else {
println("yes error")
return Result.Failure(Exception(responseJSON["err"].toString()))
}
}
catch(e: Exception) {
return Result.Failure(e)
}
}
is Result.Failure -> {
return Result.Failure(Exception(result.component2()?.localizedMessage))
}
}
}
else {
return Result.Failure(Exception("badAuth"))
}
}
An error is occurring on this line. I know this because of the print statements that are in the code:
var feed = JSONArray(responseJSON["feed"]) // <-----ERROR HERE
This is what the error that is occurring is.
[Failure: org.json.JSONException: Not a primitive array: class org.json.JSONArray]
This is what the feed object from the get request will look like, just so you have an idea of what it is:
{
"feed": [
{
"type": "post",
"slug": "equ2ZfaX2UThtkS8DzkXdc",
"author": {
"id": "00000000-0000-0000-0000-000000000000",
"name": "Archie",
"username": "archie",
"plus": true
},
"content": "I know it's quite inactive here atm. But I'm doing tons of stuff behind the scenes - basically rewriting the entire platform from scratch. Micro will be done by the end of the summer.",
"image": null,
"createdAt": "2020-07-30T20:39:23.000Z",
"score": 5,
"vote": 0,
"replyCount": 0,
"hasParent": false
}
]
}
What could possibly be going wrong here. I am using Fuel for the request, but I don't think that is the problem

Pretty sure the correct way to get the array would be to do var feed = responseJSON.getJSONArray("feed"). You're implementation calls the JSONArray(Object o) constructor which is meant to be called only for primitive arrays (int[], double[], etc.) as they cannot be effectively typed using generics). Thus the constructor complains as you pass in an object which is not a primitive array.
