[BUG]Context.SetVariable not stored in Console application running WorkflowInstance

I dev a console application , call json workflow, but the ported WriteLine activity cannot get value of variable "CurrentIndex" from custom activity :

But run in ElsaServer is OK, the value of variable is right .

`if (iterateNode != null)
{
var currentValue = _pdfProcessor?.ExtractPageAsBytes((int)currentIndex, step);
var variable1 = new Variable("CurrentIndex", currentIndex).WithWorkflowStorage();
var variable2 = new Variable("CurrentValue", currentValue).WithWorkflowStorage();

var variables = new[]
{
variable1,
variable2
};

await context.ScheduleActivityAsync(iterateNode, OnChildCompleted, variables: variables);

}`

json workflow:
