Hey, I'm having some trouble with kotlinx.serialization, I defined a class to deserialize a request, annotated it with Serializable and then from inside a route I'm calling call.receiveOrNull&lt;MyRequest&gt;()
But insted of null I'm getting an exception when the request is bad formed. Is this the expected behavior? And if yes what's the point of receiveOrNull?

I was also trying to handle exceptions, but it seems like kotlinx.serialization exceptions are internal, so I can only catch Exception? Is there some way to differentiate between the errors?

<https://youtrack.jetbrains.com/issue/KTOR-545#focus=Comments-27-4271583.0-0|Here> you can find an explanation about the `receiveOrNull` behavior logic. There is the <https://github.com/Kotlin/kotlinx.serialization/blob/master/core/commonMain/src/kotlinx/serialization/SerializationException.kt|SerializationException> that is the only public exception class. Unfortunately, there is no way to differentiate kotlinx.serialization library errors.

hey, thanks for the answer! I don't know enough about networking to think about an example for negotiation failing... anyway, am I doing it right? Do I have to catch exceptions in order to handle the bad requests?
