Hi,
I have been facing the following error lately

kotlinx.serialization compiler plugin is not applied to the module, so this annotation would not be processed. Make sure that you've setup your buildscript correctly and re-import project.

Tried searching on stackoverflow but things didn't work out.
Also, I have done same type of implemenation in 3 other Android Projects and all are working just fine.

Any help in this regard is greatly appreciated.
Thank you

Production Application crashes whenever we reach this code or is being used.

If this is related to release builds then might be a proguard issue.

This might help https://github.com/Kotlin/kotlinx.serialization#android

No, the problem is coming in the debug version itself.

[Isaac Akakpo]

Right then, maybe you don't have this in your build.gradle file ?
Kotlin :
kotlin("plugin.serialization") version "1.8.0"

Groovy :
id 'org.jetbrains.kotlin.plugin.serialization' version '1.9.21'

[Saurabh Mehta]

hmmm... So this is the current implementation I have

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript *{*
_extra_._apply_ *{*
set("kotlin_version", "1.9.21")
set("nav_version", "2.7.5")
}
_repositories_ *{*
google()
mavenCentral()
maven *{* setUrl("<https://jitpack.io>") *}*
}
dependencies *{*
val kotlinVersion = _rootProject_._extra_.get("kotlin_version")
_classpath_("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")
val navVersion = _rootProject_._extra_.get("nav_version")
_classpath_("androidx.navigation:navigation-safe-args-gradle-plugin:$navVersion")
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

plugins *{*
id("com.android.application") _version_ "8.2.0" _apply_ false
id("com.android.library") _version_ "8.2.0" _apply_ false
id("com.google.gms.google-services") _version_ "4.4.0" _apply_ false
id("com.google.devtools.ksp") _version_ "1.9.21-1.0.16" _apply_ false
id("com.google.firebase.firebase-perf") _version_ "1.4.2" _apply_ false
id("com.google.firebase.crashlytics") _version_ "2.9.9" _apply_ false
id("com.google.dagger.hilt.android") _version_ "2.48" _apply_ false
kotlin("jvm") version "1.9.21" apply false
_kotlin_("plugin.serialization") _version_ "1.9.21" _apply_ false
_kotlin_("android") _version_ "1.9.21" _apply_ false
}

[Saurabh Mehta]

While for plugins I have

plugins *{*
id("com.android.application")
id("com.google.gms.google-services")
_kotlin_("android")
id("androidx.navigation.safeargs")
id("dagger.hilt.android.plugin")
id("com.google.firebase.firebase-perf")
id("com.google.devtools.ksp")
id("kotlinx-serialization")
_kotlin_("kapt")
id("com.google.firebase.crashlytics")
}
