Hi guys, post upgrade from 1.6 to 2.0 , running into an error, calls fail with
*`Serializer for class 'JsonLiteral' is not found.`*
*`Mark the class as @Serializable or provide the serializer explicitly.HttpClientUtils`*
Request is of type  `JsonElement` . Anyone  faced something similar / any leads to look into.

This <https://youtrack.jetbrains.com/issue/KTOR-3872|discussion> may help you.

Error and use case is similar.  We were sending `Json.decodeFromString(query)`  as body. From the discussion in the link. I gather we need to
```You can either cast it or have a parameter with a concrete type```

You can make a <https://kotlinlang.org/docs/inline-functions.html#reified-type-parameters|reified type parameter> to solve your problem if you have a parameter of `Any` type.

Casting  works for us on android  as suggested in the discussion
```setBody(postBody as JsonObject)```
But, strangely fails for ios in our KMM setup.

The ios issue also came up post the upgrade but was not related to the the above discussion
