  Hi @tbentley

  Could you share;

  1. How do you call tenant creation API from public website
  2. And, which API you are calling for tenant creation ?

  Thanks,

  1. I created a MerchantController

          [HttpPost]
          public IActionResult Index(MerchantIndexViewModel input)
          {
            ...
            //validation
            ...
            //Initialize tenant object
            ...
            //Call to the API
            _tenantAppService.CreateRestaurantTenant(tenant);
  

  2. I am using a slight variation of the original CreateTenant APi adding the additional properties I needed. I kept the [UnitOfWork(IsDisabled=true] attribute on it but I also added an [AllowAnonymous] attrribute. could that be what causes the Current UnitOfWork to be nullified in CreateAsync(tenant)?

  Just tried calling the CreateRestaurantTenant(tenant) using the _tenantRegistrationAppService class and got the same error.

  Hi,

  Yes, the reason is [UnitOfWork(IsDisabled=true] attribute. If you use this attribute, you need to start a unitOfWork manually when you need it.

  using (var uow = _unitOfWorkManager.Begin())
  {
      // Here Current UnitOfWork will not be null
  }

  Thanks but I tried that if I start a new unit of work it causes the line

  CheckErrors(await _roleManager.CreateStaticRoles(tenant.Id));
  

  to give me the following error:

  System.ObjectDisposedException: Cannot access a disposed object. Object name: 'RoleManagerProxy'.

  Why does the CreateAsync(tenant) end the UnitOfWork

  using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
              {
                  //Create tenant
                  var tenant = new Tenant(tenancyName, name)
                  {
                      IsActive = isActive,
                      EditionId = editionId,
                      SubscriptionEndDateUtc = subscriptionEndDate?.ToUniversalTime(),
                      IsInTrialPeriod = isInTrialPeriod,
                      ConnectionString = connectionString.IsNullOrWhiteSpace() ? null : SimpleStringCipher.Instance.Encrypt(connectionString),
                      Address = address,
                      City = city,
                      Region = region,
                      PostalCode = postalCode,
                      Phone = phone,
                      EmailAddress = emailAddress
                  };
  
                  await CreateAsync(tenant);
                  await _unitOfWorkManager.Current.SaveChangesAsync(); //To get new tenant's id.
  
                    //We are working entities of new tenant, so changing tenant filter
                  using (_unitOfWorkManager.Current.SetTenantId(tenant.Id))
                  {
                      //Create static roles for new tenant
                      CheckErrors(await _roleManager.CreateStaticRoles(tenant.Id));
                      await _unitOfWorkManager.Current.SaveChangesAsync(); //To get static role ids

  Thank you for your help. I was able to resolve the issue.

  There were actually two things I needed to correct the problem. I didn't realize I needed the [UnitOfWork] attribute in the Controller (I had it disabled on the API) Also, I was not calling the API Asynchronously.
