Hi,

I'm getting following error when I run the find indexing job.

An exception occurred while indexing content [Link 2269__CatalogContent] [GUID 1706ee5d-d561-42ee-b6f5-d760b59fd968] [Type Product] [Name Duo Green Velvet Allesreiniger]: Value cannot be null.

This is our CatalogContentClientConventions class where we disable variant indexing and include the variants in the product:

    public class SiteCatalogContentClientConventions : CatalogContentClientConventions
    {
        protected override void ApplyProductContentConventions(EPiServer.Find.ClientConventions.TypeConventionBuilder<ProductContent> conventionBuilder)
        {
            base.ApplyProductContentConventions(conventionBuilder);

            conventionBuilder
                .ExcludeField(x => x.Variations())
                .IncludeField(y => y.VariationContents());
        }

        public override void ApplyConventions(IClientConventions clientConventions)
        {
            base.ApplyConventions(clientConventions);
            
            // Do not index variationContent
            ContentIndexer.Instance.Conventions.ForInstancesOf<VariationContent>().ShouldIndex(x => false);
            SearchClient.Instance.Conventions.NestedConventions.ForInstancesOf<ProductContent>().Add(x => x.VariationContents());
        }
    }

We use the latest implementation of find: EpiServer.Find.Framework 13.0.5 and EpiServer.Find.Commerce 11.0.2 (And commerce 12.17.1)

Any idea?

Thanks in advance!

I guess that you have a null object in the list. Let's try to check the list of variant contents for this product firstly

@Brecht: how does your VariationContents() method look like?

It had something to do with an empty CatalogKey in an IPriceValue property on our custom variant class.
I changed it to Money and it started working as expected.

Thanks for the help!
