Invalid error for decoding of nested classes

[akuleshov7]

    @Serializable
    data class Integers(
        val s: Short,
        val bool: Bool,
    )

    @Serializable
    data class Bool(val a: Boolean)

    @Test
    fun positiveParsing() {
        val test = """
                s = 5
                bool = true
            """.trimMargin()

        val decoded = Toml.decodeFromString<Integers>(test)
    }

Leads to the invalid error: Unknown key received: s

Unknown key received: s in scope <rootNode>. Switch the configuration option: 'TomlConfig.ignoreUnknownNames' to true if you would like to skip unknown keys
com.akuleshov7.ktoml.exceptions.UnknownNameException: Unknown key received: <s> in scope <rootNode>. Switch the configuration option: 'TomlConfig.ignoreUnknownNames' to true if you would like to skip unknown keys

We definitely should fail on this, but this particular error is incorrect: we should point on missing fields from bool table

Same happens with the following (when you do not provide the type):

        assertFailsWith<IllegalTypeException> { Toml.decodeFromString(test) }
