TaskOrchestrationContext GetInput Returns Null

[krieger04]

Description

After updating the Nuget package "Microsoft.Azure.Functions.Worker.Extensions.DurableTask" from 1.0.2 to 1.0.3, GetInput returns null.

await starter.ScheduleNewOrchestrationInstanceAsync("FuntionName", processingData);

[Function("FuntionName")]
public async Task ProcessOcrTaskFunction([OrchestrationTrigger] TaskOrchestrationContext context)
{
var processingData= context.GetInput(); //Returns Null
}

Just pulled my hair on this for the last couple of hours and realised upgrading to 1.0.3 from 1.0.0 which is part of the template shipped with Visual Studio 2022.

The fix has been published and will be available here: https://www.nuget.org/packages/Microsoft.Azure.WebJobs.Extensions.DurableTask/2.11.2

When using dotnet isolated (Microsoft.Azure.Functions.Worker.Extensions.DurableTask), you need only clean & rebuild your project. Microsoft.Azure.Functions.Worker.Extensions.DurableTask/1.0.3 will pull in Microsoft.Azure.WebJobs.Extensions.DurableTask/2.11.*, which should pick up the latest of 2.11.2 which includes the fix.

Primitive types seems working well, whereas passing object type throws in deserialization.

public class InputModel
{
    [JsonPropertyName("stringValue")]
    public String StringValue { get; set; }
}

[Function("RunOrchestration")]
public static Task RunOrchestration([OrchestrationTrigger] TaskOrchestrationContext context)
{
    var input = context.GetInput<InputModel>();
    Console.WriteLine(Assembly.GetAssembly(typeof(TaskOrchestrationContext)).GetName().Version);
    if (input is null)
        Console.WriteLine("INPUT IS NULL");
    else
        Console.WriteLine($"INPUT OK: {input.StringValue}");

    return Task.CompletedTask;
}
