how to fix this error:

@OptIn(ExperimentalStdlibApi::class)
    override fun <T> sign(json: T): String {
        val jsonStr = Json.encodeToString(json)
        val sign = sign(jsonStr).toHexString()
        return Json.encodeToString(SignJSON(jsonStr, sign))
    }

error is :

Cannot use 'T' as reified type parameter. Use a class instead.

encodeToString can only be called in an inline function, or you need to pass the type as an additional parameter

Thanks. Solved by moving out side of the interface definition.

@OptIn(ExperimentalStdlibApi::class)
inline fun <reified T> IInstrumentedHandler.sign(json: T): String {
    val jsonStr = Json.encodeToString(json)
    val sign = sign(jsonStr).toHexString()
    return Json.encodeToString(SignJSON(jsonStr, sign))
}
