Hi,
Looking to add custom policy and requirement based authorization to asp net zero as per: https://docs.microsoft.com/en-us/aspnet/core/security/authorization/policies?view=aspnetcore-6.0#iauthorizationservice
It is working as intended but when i try to access a default repository to check for some values it seems like it hasn't been registered and I get an error:
I'm using constructor parameter injection in the requirement handler.
System.ArgumentNullException: Value cannot be null. (Parameter 'unitOfWork') at Abp.EntityFrameworkCore.Uow.UnitOfWorkExtensions.GetDbContext[TDbContext](IActiveUnitOfWork unitOfWork, Nullable1 multiTenancySide, String name)

Any help appreciated

Ok, so I managed to get this working by injecting the UOW manager into the Authorization Handler:
using (var uow = _unitOfWorkManager.Begin()) { var exampleEntity = await _entityRepository.FirstOrDefaultAsync(entityId); var teamId = exampleEntity?.TeamId; ........ }
