DurableTaskClient.GetInstanceAsync is returning null

[84961]

Description

I am upgrading my .NET 6 Durable function app to .NET 8 .The overall function is working after the upgrade. There was a custom status endpoint which queries using the orchestration id ,that particular piece of code is not working. The DurableTaskClient GetInstanceAsync method invoked by passing the instance id is always returning null.

Expected behavior

Expected to retrieve the custom status set for the orchestration id

Actual behavior

the method call returns only null result

// insert code snippet here


   [Function(nameof(ExportStatus))]
   public async Task<IActionResult> Run(
                                               [HttpTrigger(AuthorizationLevel.Function, methods: "get", Route = "sample/{instanceId}/status")] 
                                               HttpRequest req,
                                               [DurableClient] DurableTaskClient orchestrationClient,
                                               string instanceId)
     {

       var status = await orchestrationClient.GetInstanceAsync(instanceId, true);
       if (status != null) {
       }
}
