kotlinx.serialization.protobuf.internal.ObjectEncoder does not define or inherit an implementation of the resolved method abstract void encodeNullableSerializableValue

getting in error when implementing this library into our project:

Receiver class kotlinx.serialization.protobuf.internal.ObjectEncoder does not define or inherit an implementation of the resolved method 'abstract void encodeNullableSerializableValue(kotlinx.serialization.SerializationStrategy, java.lang.Object)' of interface kotlinx.serialization.encoding.Encoder.

Created the smallest version of our project that still reproduces the issue for me: https://github.com/casvanluijtelaar/suspend-transform-error-demo

The temporary workaround still seems effective: you can try adding the kotlinx-serialization-protobuf dependency in buildSrc/build.gradle.kts to ensure consistent serialization versions across the build environment.

// the `buildSrc/build.gradle.kts`

dependencies {
    implementation(libs.android.gradlePlugin)
    implementation(libs.kotlin.gradlePlugin)
    implementation(libs.dokka.gradlePlugin)
    implementation(libs.kotlin.compiler.embeddable)
+   implementation(libs.kotlinx.serialization.protobuf)
}

The build environment does indeed have a serialization dependency, it comes from Dokka: org.jetbrains.dokka:dokka-gradle-plugin.
