Jackson deserialization issue with Kotlin and data classes

调研方向
从 build.gradle.kts 开始,将与 Azurite 一起使用的依赖项设置与 Azure 中使用的设置进行比较。跟踪为已部署的 Kotlin 工作负载配置 durable task data converter 的方式;当 OrchestratorInput 和类似的 Kotlin 数据类能够在 Azure 中不使用默认构造函数值进行反序列化时,即视为完成。

描述
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",
"lastUpdatedTime": "2026-03-10T11:31:39Z"
}
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.
