Vote:
 

We`ve got a problem on one of our environments, when we open commerce tab and go to SKU edit page, the page cannot be loaded.

I checked outcoming requests and find one, that failed:

We tried to investigate this issue, but with no result.

Could you please explain what can be the potential issue or where we should see to find the origin of the problem.

It looks like one or more media associated with the SKU was deleted. You would need to remove that media by code. (Probably by using a scheduled job to iterate over the entries and remove assets that no longer exist).

In later versions we made it more defensive in this case

Thanks for your answer, now it`s a bit more clear. 

Do I understand correctly, that we should iterate through sku`s images(in CommerceMediaCollection property) and remove items that are null?

pseudo code

var mediaToDelete = new List<CommerceMedia>();

foreach (CommerceMedia item in entry.CommerceMediaCollection)

{

 if(!contentLoader.TryGet<IContentMedia>(item.AssetLink, out IContentMedia _)

{

 mediaToDelete.Add(item);

}

}

foreach( var itemToDelete in mediaToDelete)

{

 entry.CommerceMediaCollection.Remove(itemToDelete);

}

//save the entry

I tried this solution and unfortunately - it is not working.


I also deleted all media files attached to sku programmatically. But page still cannot be loaded.

Did you save the entry?

Yes,

// pseudo code

var sku = contentRepository.Get(...);

sku.CommerceMediaCollection.Clean();

contentRepository.Publish(sku);

Just to make sure, you clear the CommerceMediaCollection of the entry that failed to load, right? And the error is the same?

And did you try to access 

<yoursite>/episerver/Commerce/Catalog#context=epi.cms.contentdata:///780520__CatalogContent&viewsetting=viewlanguage:///en ?

It is possible that you are trying to load an older version with the old CommerceMediaCollection intact.
