Application interaction -> Task/{taskID}/complete does'nt run as expected

[dbornawidacom]

I use Elsa 3.5.3, MS-SQL-Server. I want to build a application to procced "RunTask"

I have build this workflow.

I complete task inj this code.

public async Task CompleteTaskAndResumeWorkflowAsync(
string taskId,
string workflowInstanceId,
string subStatus = "Finished",
object? result = null,
CancellationToken cancellationToken = default)
{
// 1️⃣ Task Complete aufrufen
var completePayload = new
{
status = "approved",
subStatus = "Done",
result = "Done"
};

var completeUrl = new Uri($"elsa/api/tasks/{taskId}/complete", UriKind.Relative);
using var completeResponse = await _httpClient.PostAsJsonAsync(
    completeUrl, completePayload, cancellationToken);

var completeResponseBody = await completeResponse.Content.ReadAsStringAsync(cancellationToken);

if (!completeResponse.IsSuccessStatusCode)
    throw new Exception($"Task completion failed: {completeResponse.StatusCode} - {completeResponseBody}");

return "ok";           

}

Than workflow run like this picture, but the workflow doesn't go to state fnished.

Any Ideas?
