ArgumentOutOfRangeException When Reference Field is Unset on Content

[HegyiOliver]

An ArgumentOutOfRangeException occurs when executing a SenseNet client query function like Task<IContentCollection<Content>> QueryAsync(QueryContentRequest requestData, CancellationToken cancel). This error is triggered if any of the collected content's selected reference fields are not set.

My Query Details

• Expand Fields: ArticleReference
• Select Fields:

  Path, Type, Name, Id, DisplayName, ParentPath, Hidden, Index,
  ArticleReference/Path, ArticleReference/Type, ArticleReference/Name,
  ArticleReference/Id, ArticleReference/DisplayName, ArticleReference/ParentPath,
  ArticleReference/Hidden, ArticleReference/Index, LinkOpenType, Alt, Title,
  Href, HrefTitle, Description
  

Probable Cause

The error is likely thrown in the method SenseNet.Client.Repository.CreateContentFromResponse(Object jObject, Type defaultContentType).

Stack Trace

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

Steps to Reproduce

1. Create a query with the specified expand and select fields.
2. Execute the query using QueryAsync method.
3. Ensure at least one of the collected content's reference fields is unset.
4. Observe the ArgumentOutOfRangeException thrown.

Expected Behavior

The query should handle cases where reference fields are unset without throwing an exception.
