How do I get a YesSQL ISession during a Rewrite Rule?

I'm running Orchard Core and have created a custom IRule that needs to query the Content Items. (Obviously querying the DB is time-consuming, so we only do this if something happened and we need to rebuild our redirects cache.) To do so, I am getting an IOrchardHelper from the service provider, and using that helper, I'm executing

var listCi = await orchardHelper.GetContentItemByAliasAsync("redirects-list", false);

However, this is throwing a NullReferenceException, because GetService<ISession>() returns null, but AliasPartContentHandleHelper.QueryAliasIndex(session, alias) assumes that session is non-null.

Is there anyway to adjust things so that GetService<ISession>() returns a session?

You can resolve the current tenants scoped service provider by using the accessor

var session = ShellScope.Current.ServiceProvider.GetRequiredService<ISession>();

and query your content item from there (you probably won't be able to use the IOrchardCoreHelper methods), so make an ISession query directly. Something like

var content = _session.Query<ContentItem, AliasPartIndex>(x => x.Alias == "youralias");

However, be a little wary, as this returns the current tenants shell scope, so will vary by tenant, and you will have to make sure your rewrite middleware is added after the orchard core middleware, so you are in the correct scope.
