Jackson deserialization issue with Kotlin and data classes

I have a simple durable orchestration function written in Kotlin who's input type is

data class OrchestratorInput(val value: String)

When I run my orchestration, it fails to deserialize JSON text into an instance of OrchestratorInput, probably because data classes in Kotlin does not have any no-arg constructor unless I assign default values to all fields of the class. The output of the orchestration is shown below, containing the error message:

{
  "name": "OrchestrationFunction",
  "instanceId": "f340b4b5-b04d-43a0-bd83-40a12ab419ec",
  "runtimeStatus": "Failed",
  "input": {
    "value": "hello, world!"
  },
  "customStatus": "",
  "output": "com.microsoft.durabletask.DataConverter$DataConverterException: Failed to deserialize the JSON text to org.example.OrchestratorInput. Detailed error message: Cannot construct instance of `org.example.OrchestratorInput` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)\n at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 1, column: 2]",
  "createdTime": "2026-03-10T11:31:29Z",

}

Adding jackson-module-kotlin to build.gradle.kts did not help, although it helped when running the orchestration locally with Azurite

implementation("com.fasterxml.jackson.module:jackson-module-kotlin:2.21.1")

For some reason the module is not picked up when running in Azure. Is there any way to fix this? Now I'm forced to assign default values to every field of every data class used as input or output of orchestration- and activity functions, which makes the code very verbose.

Beginne mit build.gradle.kts und vergleiche die verwendete Dependency-Konfiguration mit Azurite mit der in Azure verwendeten. Verfolge, wie der durable task data converter für bereitgestellte Kotlin-Workloads konfiguriert ist; als erledigt gilt die Aufgabe, wenn OrchestratorInput und ähnliche Kotlin-Datenklassen in Azure ohne Standardkonstruktorwerte deserialisiert werden.
