I got the app up and running. Started up, it was working fine. I checked in the code, and when another developer started the app (database is created and tables exist) he gets the following error:
There is no tenant with given id: 1 Abp.MultiTenancy.TenantCache<TTenant, TUser>.Get(int tenantId) in TenantCache.cs, line 35
I don't remember doing anything specific when I first started the app. When I look in my database, I have a record in AbpTenant, when he looks in his, there is no record. Any ideas?
Thanks,
Matt

Is the primary key id of the data in the Abp Tenants table a number 1?
If you are just starting the project, you can delete the database and re-migrate.

It is a fresh database, all they have done is run Update-Database, and then start the application.

Can you share the complete stack information?
You can try to modify the database name of the database connection string, re-migrate and start the application to see if it is still wrong.

It seems that what caused the tenant 1 does not exist.

Thanks for your help on resolving this problem. I'm posting the solution for others who may also experience this issue.
**Hi,
Thank you for sharing your solution. It seems like there is a bug for single tenant mode.
Please change Exist method of DatabaseCheckHelper class (which is under src\xxx.EntityFrameworkCore\EntityFrameworkCore) like below;**
public bool Exist(string connectionString) { if (connectionString.IsNullOrEmpty()) { //connectionString is null for unit tests return true; } try { using (var uow =_unitOfWorkManager.Begin()) { using (_unitOfWorkManager.Current.SetTenantId(null)) { _dbContextProvider.GetDbContext().Database.OpenConnection(); uow.Complete(); } } } catch (Exception ex) { return false; } return true; } -
