please help me fix this bug on ASP.NET C#. Text does not automatically revert after a failed update/creation of a new Portfolio

public ManagePortfolioGridViewModel UpdatePortfolio(ManagePortfolioGridViewModel vm) { using var uow = new UnitOfWork(new MobilebdContext()); var existingPortfolioWithSameName = uow.Portfolios.Find(t => t.Name == vm.Name.Trim()) .ToList();

var existingPortfolioWithSameAbbreviation = uow.Portfolios.Find(t => t.Abbreviation == vm.Abbreviation.Trim()) .ToList();

if (existingPortfolioWithSameName.Any()) { if (existingPortfolioWithSameName.Count != 1) { throw new Exception("Multiple Portfolios with this name already exists."); }

var isSamePortfolio = existingPortfolioWithSameName[0].Id == vm.Id;

if (!isSamePortfolio) { throw new Exception("A Portfolio with this name already exists."); } } if (existingPortfolioWithSameAbbreviation.Any()) { if (existingPortfolioWithSameAbbreviation.Count != 1) { throw new Exception("Multiple Portfolios with this abbriviation already exists."); }

var isSamePortfolio = existingPortfolioWithSameAbbreviation[0].Id == vm.Id;

if (!isSamePortfolio) { throw new Exception("A Portfolio with this abbriviation already exists."); } }

var newPortfolio = uow.Portfolios.Get(vm.Id);

newPortfolio.Name = vm.Name; newPortfolio.RevenueTarget = vm.RevenueTarget; newPortfolio.Abbreviation = vm.Abbreviation;

uow.Complete();

return vm; }
