[Bug with optimizers]

[AndraxDev]

Description

Mark the class as @serializable or provide the serializer explicitly exception occurs when optimizers and obfuscators are used.

Steps to Reproduce

1. Compile this API with R8 or ProGuard optimizer
2. Obfuscate the solution

Environment

• openai-kotlin version: 3.2.0
• Kotlin version: 1.7.21
• OS: Windows 11

Additional Info

Code sample:

val completions: Flow<ChatCompletionChunk> = ai!!.chatCompletions(chatCompletionRequest)

Note

It works fine without optimizers

Stacktrace:

Process: org.teslasoft.assistant, PID: 766
b6.h: Serializer for class 'b' is not found.

Can't add "bug" label. Maybe I haven't permissions?

[aallam]

You can incorporate the following rules:

-keepattributes InnerClasses

-if @kotlinx.serialization.Serializable class
com.aallam.openai.api.**,
com.aallam.openai.client.internal.data.**

{
    static **$* *;
}
-keepnames class <1>$$serializer {
    static <1>$$serializer INSTANCE;
}

The upcoming release should include these rules directly within the library.
