Are they known bugs with sealed classes in 1.2.1 in JS/JVM?
val data: Data
where Data is a sealed class gives me

"data": {
	"type": "SIMPLE",
	"id": "TEXT"
}

on JS, and

"data": [
	"SIMPLE",
	{
		"id": "TEXT"
	}
]

on JVM, which unsurprisingly completely fails when Ktor tries to send messages between them.

Did you enable arrayPolymorphism maybe?

[CLOVIS]

After calling Json.encodeToString & decodeFromString manually from both sides (instead of letting Ktor do it), the problem is gone.

[CLOVIS]

Maybe Ktor enabled that option? I definitely didn't explicitely enable anything

[CLOVIS]

What is arrayPolymorphism? I can't find it in the wiki

Grr Ktor, Thanks Dominic you've got good intuition

I think ktor 1.6 somehow flipped the useArrayPolymorphism for the client: https://kotlinlang.slack.com/archives/C0A974TJ9/p1623504933235100

You just referenced my own thread to me ^^

But yeah, I posted here first, thanks to Dominic I understood it was Ktor's fault, and then posted in #ktor
