Error Mappin Expression type

Source/destination types

public Expression<Func<TModel, bool>> ToModelExpression(Expression<Func<TViewModel, bool>> expression)
        {
            var cfg = _autoMaperConfiguration.Configuration().CreateMapper();
            var exp = cfg.Map<Expression<Func<TViewModel, bool>>, Expression<Func<TModel, bool>>>(expression);
            return exp;
        }

Mapping configuration

// Mapper.Initialize or just the CreateMap snippet 

Version: x.y.z

Version 7.0.1

Expected behavior

i want map

Actual behavior

i use top code to map expression type. but occured this error :

ParameterExpression of type ‘Co.Domino.Service.Account.ViewModel.AccountViewModel’ cannot be used for delegate parameter of type ‘Co.Domino.Model.Account.AccountModel’

Automapper return this :

.Lambda #Lambda1<System.Func`2[Co.Domino.Model.Account.AccountModel,System.Boolean]>(Co.Domino.Service.Account.ViewModel.AccountViewModel $m) { (System.Int32)($m.AccountGroup).AccountType == (System.Int32).Constant<Co.Domino.WinUI.Windows.Invoice.PageViewInvoices>(Co.Domino.WinUI.Windows.Invoice.PageViewInvoices)._selectedtAccountType && .Call ($m.Name).Contains(.Constant<Co.Domino.WinUI.Windows.Invoice.PageViewInvoices>(Co.Domino.WinUI.Windows.Invoice.PageViewInvoices)._filter) }

why still lambda parameters is AccountModel!!!

It’s still the wrong repository. This behavior was split out. Check out https://github.com/AutoMapper/AutoMapper.Extensions.ExpressionMapping
