[C#] 비 정적 방법에는 대상이 필요합니다

Firefox는 로컬 및 프로덕션 모두에서, IE 로컬에서는 IE에서 작동하지만 프로덕션에서는 IE에서는 잘 작동하는 컨트롤러 작업이 있습니다. 내 컨트롤러 작업은 다음과 같습니다.

public ActionResult MNPurchase()
{
    CalculationViewModel calculationViewModel = (CalculationViewModel)TempData["calculationViewModel"];

    decimal OP = landTitleUnitOfWork.Sales.Find()
        .Where(x => x.Min >= calculationViewModel.SalesPrice)
        .FirstOrDefault()
        .OP;

    decimal MP = landTitleUnitOfWork.Sales.Find()
        .Where(x => x.Min >= calculationViewModel.MortgageAmount)
        .FirstOrDefault()
        .MP;

    calculationViewModel.LoanAmount = (OP + 100) - MP;
    calculationViewModel.LendersTitleInsurance = (calculationViewModel.LoanAmount + 850);

    return View(calculationViewModel);
}

IE에서 얻는 스택 추적은 다음과 같습니다.
