Search & Navigation Content Indexing Job fails both on DXP and locally

I'm getting this error recently when trying to do a re-index of a site. The re-index job will run for 15 seconds then just stop.

EPiServer.Find.Cms.ContentIndexer: Error: 148-JCRXXY2 An exception occurred while fetching content. Invalid operation. The connection is closed..
System.InvalidOperationException: Invalid operation. The connection is closed.

On DXP I also get this kind of error with the same result that not all items are indexed

System.InvalidOperationException: Cannot create a command without an existing connection, you can use DbFactory to create stand-alone command objects

at EPiServer.Framework.Cache.ObjectInstanceCacheExtensions.ReadThroughWithWait[T](IObjectInstanceCache cache, String cacheKey, Func`1 readValue, Func`2 evictionPolicy)

Weird part is that if I try to index the site via code everything works as expected which tells me that there's maybe something wrong in Epis internal classes? I Tried this snippet just to see if something crashed and it ran without a problem.

var contentItems = _contentLoader.GetDescendents(ContentReference.StartPage).Select(x => _contentLoader.Get<IContent>(x)).ToList();
foreach (var contentItem in contentItems)
{
    SearchClient.Instance.Index(contentItem);
}

Did you find any solution to this, Alexander?

I'm facing the same issue starting from EPiServer.CMS 12.22.2. With 12.22.1, the indexing job seems to work just fine.

I'm afraid not. But I've opened a ticket with Optimizely support so they can look at the problem. I'll get back to you once I've got any answers.

This will be fixed with next CMS and Find package

CMS-29569 BackgroundContext should be isolated
