how to add parameters to a class constructor？
I want to add parameters to a primary constructor in SyntheticResolveExtension, but it failed
the code is：
in SyntheticResolveExtension:
override fun generateSyntheticClasses(
thisDescriptor: ClassDescriptor,
name: Name,
ctx: LazyClassContext,
declarationProvider: ClassMemberDeclarationProvider,
result: MutableSet<ClassDescriptor>
) {
if (!thisDescriptor.annotatedAsDeepCopiableDataClass()) {
return
}
if(name.identifier=="sub") {
result += trackableSubClass(thisDescriptor);
}

}

private fun trackableSubClass(
thisDescriptor: ClassDescriptor
): ClassDescriptorImpl = object : ClassDescriptorImpl(
thisDescriptor,
Name.identifier(SUBCLASS_NAME),
Modality.FINAL,
ClassKind.CLASS,
emptyList<KotlinType>(),
thisDescriptor.source,
false,
LockBasedStorageManager.NO_LOCKS
) {
override fun getUnsubstitutedMemberScope(): MemberScope {
return MemberScope.Empty
}

}.apply {

val a = ClassConstructorDescriptorImpl.create(
this,
Annotations.EMPTY,
true,
this.source
)
val b = ValueParameterDescriptorImpl(
containingDeclaration = a,
original = null,
index = 0,
annotations = Annotations.EMPTY,
name = Name.identifier("d"),
outType = thisDescriptor.builtIns.longType,
declaresDefaultValue = true,
isCrossinline = false,
isNoinline = false,
varargElementType = null,
source = a.source,
)

a.initialize(
listOf(b),
DescriptorVisibilities.PUBLIC,
)
a.returnType = this.defaultType
this.initialize(
MemberScope.Empty,
setOf(a),
a
)
}

in IrElementTransformerVoidWithContext:

fun IrClass.createSub(pluginContext: IrPluginContext){
val constructorOfAny = pluginContext.irBuiltIns.anyClass.owner.constructors.first()
primaryConstructor!!.body=factory.createBlockBody(
startOffset, endOffset,
listOf(
IrDelegatingConstructorCallImpl(
startOffset, endOffset, pluginContext.irBuiltIns.unitType,
constructorOfAny.symbol, 0,
constructorOfAny.valueParameters.size
).apply {
primaryConstructor!!.valueParameters.forEachIndexed { idx, parameter ->
println(idx)
println(parameter)
putValueArgument(idx, IrGetValueImpl(startOffset, endOffset, parameter.type, parameter.symbol))
}
},
IrInstanceInitializerCallImpl(startOffset, endOffset, symbol, pluginContext.irBuiltIns.unitType)
)
)
}

the error is :
e: java.lang.AssertionError: org.jetbrains.kotlin.ir.expressions.impl.IrDelegatingConstructorCallImpl@2169d6d4: No such value argument slot: 0
