General Info

• I am using the latest version
• I checked the troubleshooting page for similar problems

Version(s)

3.0.1

Kotlin Target(s) and their respective versions

JVM 21

What happened? (include your code)

With Proguard:
Serializer for class 'RealtimeMessage' is not found.
Please ensure that class is marked as '@serializable' and that the serialization compiler plugin is applied.

Without Proguard it works.

I have even tried an extreme rule:
-keep @kotlinx.serialization.Serializable class * {*;}
But didn't help.

Steps To Reproduce (optional)

No response

Relevant log output (optional)

No response

-keep class io.github.jan.** { *;}

Also, This worked for now, but would like to remove this, since it obfuscation than loses its point.

I don't have this issue. Can you share your library versions and build files?

Is this the project affected? The Supabase modules are declared but not used in any build file

[Shabinder]

This catalog is used in the project, so can refer versions, project itself isn't open source.

Well, can you make a reproducer? Normally if there is an issue with serializers for libraries not found, the serialization plugin was applied incorrectly. E.g. the serialization plugin has to also be applied in the project-wide build.gradle.kts

Yes, that's confirmed here, since adding -keep class io.github.jan.** { *;} fixes the issue.
Also, I noticed this is happening only in compose desktop target, android target runs fine.

I don't think there is anything I can do since it a Ktor / KotlinX Serialization issue.
