I have an issue exactly similar to this

Items appear in SXA scope but not in search results

and here is my sitecore log

This bit:

Message: Object reference not set to an instance of an object.
Source: Sitecore.XA.Foundation.SitecoreExtensions
   at Sitecore.XA.Foundation.SitecoreExtensions.Extensions.ItemExtensions.FirstChildInheritingFrom(Item item, ID templateId)

especially FirstChildInheritingFrom might mean that SXA has not been properly installed (e.g.: some templates are missing).

Exception System.NullReferenceException, Message: Object reference not set to an instance of an object means that you are using default host header of Sitecore instead of host header of your SXA site.

To solve your problem:

  1. Browse using your SXA Host Header Url.
  2. Check that Solr Cores sitecore_sxa_master_index and sitecore_sxa_web_index exist.

If they don't, create them using the following command:

solr create_core -c new_core -d basic_configs
  1. Populate schema and rebuild index.
