When Injecting IBackgroundManager into an AppService as per the documentation I receive the following Exception:

Error [10:48:53 ERR] ---------- RemoteServiceErrorInfo ---------- { "code": null, "message": "An internal error occurred during your request!", "details": null, "data": { "ActivatorChain": "Castle.Proxies.AchievementRegistersAppServiceProxy" }, "validationErrors": null }

Code

    public class AchievementRegistersAppService : ApplicationService, IAchievementRegistersAppService
    {
        private readonly IAchievementRegisterRepository _achievementRegisterRepository;
        private readonly IBackgroundJobManager _backgroundJobManager;

        public AchievementRegistersAppService(IAchievementRegisterRepository achievementRegisterRepository, IBackgroundJobManager backgroundJobManager)
        {
            _achievementRegisterRepository = achievementRegisterRepository;
            _backgroundJobManager = backgroundJobManager;


        }

Also when defining a Job I receive the following error unless I derive it from Abp.BackgroundJobs.IBackgroundJobBase<NZQAUnitsImportArgs>

'IBackgroundJobManager.EnqueueAsync<TJob, TArgs>(TArgs, BackgroundJobPriority, TimeSpan?)'. There is no implicit reference conversion from 'ePlus.BackgroundJobs.NZQAUnitsImportJob' to 'Abp.BackgroundJobs.IBackgroundJobBase<ePlus.BackgroundJobs.NZQAUnitsImportArgs>'.

Job Definition

public class NZQAUnitsImportJob : AsyncBackgroundJob<NZQAUnitsImportArgs>, ITransientDependency

**Enqueue**
 var Args = new NZQAUnitsImportArgs
            { ......... }
await _backgroundJobManager.EnqueueAsync<NZQAUnitsImportJob, NZQAUnitsImportArgs>(Args);
