Hello,

After two days of strugle with this issue, I'm (partially) giving up. Long story short - I have a custom CatalogContentProvider that works very well in the Admin UI - I can see the category (nodes) tree as expected and everything works very well.

There are two big problems and I really hope that someone can lead me in the correct direction:

a) Though the nodes tree is displayed correctly, the "Belongs to / Primary category" tab is empty - it doesn't display anything.

b) I don't know if it's related or not, if I'm trying to access a node (category) in the browser, I always receive 404 for all categories retrieved through the CatalogContentProvider; for all the others, everything is working well and I can see the categories in the browser.

First, regarding the versions of the packages that I'm using:

<PackageReference Include="EPiServer.Commerce" Version="14.33.0" />

Second, regarding the creation of the category through the custom catalog content provider, this is what I'm setting:

        T entryContentBase = this.contentRepository.GetDefault<T>(parentContentReference);
        
        entryContentBase.Language = new CultureInfo(currentCatalog.Language.Name);
        entryContentBase.MasterLanguage = new CultureInfo(currentCatalog.MasterLanguage.Name);
        
        entryContentBase.ExistingLanguages =
            new List<CultureInfo>() { new CultureInfo(currentCatalog.Language.Name) };

        entryContentBase.Name = itemName;
        entryContentBase.ContentLink = contentLink;
        entryContentBase.ContentGuid = contentGuid;

        entryContentBase.ParentLink = parentContentReference;
        entryContentBase.IsDeleted = false;
        entryContentBase.IsPendingPublish = false;
        entryContentBase.StartPublish = DateTime.Now.AddYears(-1);
        entryContentBase.Property.Add("Epi_StartPublish", new PropertyDate(entryContentBase.StartPublish.Value));
        entryContentBase.Status = VersionStatus.Published;
        entryContentBase.Property.Add("Epi_IsPublished", new PropertyBoolean(true));
        entryContentBase.StopPublish = DateTime.Now.AddYears(1);
        entryContentBase.Property.Add("Epi_StopPublish", new PropertyDate(entryContentBase.StopPublish.Value));
        entryContentBase.CatalogId = currentCatalog.CatalogId;
        entryContentBase.IsModified = false;

So, as you can see - the parent link is set.

And this is how the admin UI looks like:

Is there someone who can, please, have an idea about why this is empty or why the category is not being displayed in the browser and throw 404?

BTW, if I'm trying to open a category URL that comes through the custom CatalogContentProvider, this is what I see in the error log:

Request reached the end of the middleware pipeline without being handled by application code.

Thank you very much!
