When impersonating a User after logging in as tenant admin the code does not throw an exception. When impersonating a User after logging in as host atmin the code throws an exception.

When impersonating a User after logging in as host admin, the Exception identified at the start of this post ("There is no user with id: 1") is thrown when _userManager.GetUserByIdAsync(currentUser.Value); is called.

Specific steps:

login as host admin

navigate to 'Tenants'

Under 'Actions', select 'Login as this tenant'

Select a non-admin tenant to impersonate. The impersonated User's id is 4, however currentUser.Value = 1, which is the host admin Id.

Hi @timmackey

Does this happen during development tiem or production ? If it is production, do you use sbudomain name as tenancy name ?

Thanks,

This happens during development. The only way to obtain the screenshot above is with a Debug build. The tenancy name is NOT being used as a subdomain, although I would like to be able to do that in the future.

hi timmackey

You can try the SetTenantId method to switch the tenant of the current unit of work.

Because the host user cannot be queried under the tenant

   using (_unitOfWorkManager.Current.SetTenantId(tenantId))
    {
        var susr = AbpSession.ImpersonatorUserId > 0
                 ? AbpSession.ImpersonatorUserId
                 : AbpSession.UserId;

        var rler = await _userManager.GetUserByIdAsync(susr.Value);
        var rlerRoles = await _userManager.GetRolesAsync(rler);
    }

The solution I settled on was to test if (AbpSession.ImpersonatorUserId == 1), then don't call _userManager.GetUserByIdAsync, since by definition if the UserId is 1, then I know who the user is - the host admin.
