Elasticsearch NEST - System.StackOverflowException when running Index

Question

When I run this code:

var result = _client.Index<EntityType>(item, i => i.Index(n));

I'm getting this error:

Exception has occurred: CLR/System.StackOverflowException An unhandled exception of type 'System.StackOverflowException' occurred in Elasticsearch.Net.dll

The full method:

public bool Index<EntityType>(EntityType item, int attempt = 0) where EntityType : class, IDomainEntity<int>
{
    const int maxRetries = 5;
    if (item == null)
    {
        return false;
    }
    var type = item.GetType();
    var attributes = type.CustomAttributes;
    string n = "";

    foreach (var attribute in attributes)
    {
        foreach (var arg in attribute.NamedArguments)
        {
            if (arg.MemberName == "RelationName")
            {
                n = arg.TypedValue.Value.ToString().ToLower();
            }
        }
    }

    var result = _client.Index<EntityType>(item, i => i.Index(n));
    if (!CheckResponse(result) && attempt < maxRetries)
    {
        RefreshClient<EntityType>();
        attempt++;
        return Index(item, attempt);
    }
    RefreshClient<EntityType>();
    return result.IsValid;
}

Ah sorry, I missed that (late late night :)) Do you have a complete reproducible example that can be shared (here or as a gist)? — Russ Cam

@RussCam I actually think it might be the same as your other answer, I had linked that in my question before realising you had answered it. — BeniaminoBaggins

I added [PropertyName("propertyToIgnoreInElasticsearch", Ignore = true)] from NEST to my POCO fields which were causing an infinite loop while Indexing. It ignores a field from the Elasticsearch Index so it is not indexed.

for example:

[Serializable]
public abstract class VeganItem<VeganItemEstablishmentType>
{
    [Required]
    public string Name { get; set; }

    [PropertyName("veganItemEstablishments", Ignore = true)]
    public virtual ICollection<VeganItemEstablishmentType> VeganItemEstablishments { get; set; }
}

I'm glad to see you got it sorted. In general, it's better to create specific POCOs for interacting with Elasticsearch. Complex objects such as those used with ORMs like Entity Framework and NHibernate that can include lazily loaded entities and self-referencing loops can cause problems when serializing to JSON, to send to Elasticsearch
