  Hi,

  We didn't have this error before ?

  Does it happen with same connectionString ? First you get error then after a few trials you manage to create tenant and database ?

  And is your Sql Server on a local server ?

  Below is the code which we wrote for creating the Tenant. We copied from the existing code and made some modification. We are adding an Organization Id to the tenant.

  Also it's withing the same database and the database is not local.

  public async Task<int> CreateWithAdminUserAsync(string tenancyName, string name, string adminPassword, string adminEmailAddress, bool isActive, int? editionId, bool shouldChangePasswordOnNextLogin,
              bool sendActivationEmail, long? organizationId, int? sourcetenantId, List<string> entityList)
          {
              int newTenantId;
              long newAdminId;
  
              using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
              {
  
                  var connectionstringUnit = await (from org in _organizationRepository.GetAll()
                                                    join constr in _connectionStringRepository.GetAll() on org.ConnectionStringId equals
                                                        constr.Id
                                                    where org.Id == organizationId
                                                    select constr).FirstOrDefaultAsync();
  
                  //Create tenant
                  var tenant = new Tenant(tenancyName, name)
                  {
                      IsActive = isActive,
                      EditionId = editionId,
                      ConnectionString = ReferenceEquals(connectionstringUnit, null) ? null : connectionstringUnit.ConnectionString,
                      OrganizationUnitId = organizationId
                  };

                  if (sourcetenantId.HasValue)

              //Used a second UOW since UOW above sets some permissions and _notificationSubscriptionManager.SubscribeToAllAvailableNotificationsAsync needs these permissions to be saved.
              using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
              {
                  using (_unitOfWorkManager.Current.SetTenantId(newTenantId))
                  {
                      await _notificationSubscriptionManager.SubscribeToAllAvailableNotificationsAsync(new UserIdentifier(newTenantId, newAdminId));
                      await _unitOfWorkManager.Current.SaveChangesAsync();
                      await uow.CompleteAsync();
                  }
              }
  
              return newTenantId;
          }
  

  Do you find any issue with this code ?

  Hi,

  Can you try to move added codes in a seperate unitOfWork ?

  Move these lines before first unitOfWork and put it inside another unit of work

  var connectionstringUnit = await (from org in _organizationRepository.GetAll()
                                join constr in _connectionStringRepository.GetAll() on org.ConnectionStringId equals
                                    constr.Id
                                where org.Id == organizationId
                                select constr).FirstOrDefaultAsync();
  

  and put CloneTenantData just before these lines and put it in a new unitOfWork

  //Used a second UOW since UOW above sets some permissions and _notificationSubscriptionManager.SubscribeToAllAvailableNotificationsAsync needs these permissions to be saved.
  using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
  

  Can you also share CloneTenantData code if this does not work for you ?

  Thanks.
