I haven’t changed anything with the .NET 8 angular template except configure it to use OrmLite

Any ideas where to look?

The Exception is thrown trying to verify the Users password, I’m assuming either the User wasn’t configured with a Password or no password was provided, in which case it might be a serialization issue where the Password wasn’t sent correctly.

Tracked it down. The following was interfering with the auth process

OrmLiteConfig.OnDbNullFilter = fieldDef => 
                fieldDef.FieldType == typeof(string)
                    ? ""
                    : null;

Removing this fixed it
