Hi all

We have built a scheduled job to clear our catalog for "dead links" to assets. The job loops over all entries in our catalog and finds "dead links" and removed these, inspired by this article.
However, we experience, that the "dead links" are not removed in commerce. When debugging, we see the assets being identified and removed from CommerceMediaCollection. When we check commerce UI the assets are still visible with the message "Media not found". If I manually change a random value on the given item in commerce and publish it, everything works fine and the assets are gone.

Below is the code doing the work.
EPiServer CMS v10.10.0.0
EPiServer Commerce v10.7.2.0

var catalogItem = _contentRepository.Get<CatalogContentBase>(catalogItemReference);

if (catalogItem != null && catalogItem is EntryContentBase)
{
    try
    {
        var clone = catalogItem.CreateWritableClone<EntryContentBase>();

        var unlinkedAssetsDeletedLocal = 0;
        var unlinkedAssets = clone.CommerceMediaCollection.Where(x => ContentReference.IsNullOrEmpty(x.AssetLink)).ToList();
        foreach(var unlinkedAsset in unlinkedAssets)
        {
            clone.CommerceMediaCollection.Remove(unlinkedAsset);
        }
        _contentRepository.Save(clone, SaveAction.Publish, AccessLevel.NoAccess);
    }
    catch (Exception ex)
    {
        _logger.Error(nameof(RemoveDeadMediaLinksCommerceJob) + ": " + ex.Message, ex);
    }
}
