Line 56 is if(!input.readUTF8LineTo(stringBuilder)) throw Exception("BasicConnection.kt: Unknow error!")

[gildor]

No, I suppose this is wrong line

[gildor]

data not initilised in case of error

[gildor]

so when you try to return it you get this crash

[gildor]

just rewrite your code. You don’t need lateinit

[gildor]

val data =  try {
            var stringBuilder: StringBuilder = StringBuilder()
            if(!input.readUTF8LineTo(stringBuilder)) throw Exception("BasicConnection.kt: Unknow error!")
            data = stringBuilder.substring(0,stringBuilder.indexOf("\r\n"))
        } catch (e: Throwable) {
            e.printStackTrace()
            socket.close()
            connected = false
           null // or any other default value
        }

or even more simple solution, but not so idiomatic:

var data: String
        try {
            data = "success"
        } catch(e: Throwable) {
            data = "error"
        }
        return data

ok thnx

[otakusenpai]

fun receiveData() = runBlocking {
var data = try {
var stringBuilder: StringBuilder = StringBuilder()
if(!input.readUTF8LineTo(stringBuilder)) throw Exception("BasicConnection.kt: Unknow error!")
stringBuilder.substring(0,stringBuilder.indexOf("\r\n"))
} catch (e: Throwable) {
e.printStackTrace()
socket.close()
connected = false
null
}
data
}
