    • The error JsonObjectCreationHandling.Populate is incompatible with reference handling occurs when System.Text.Json serialization options are misconfigured, often due to incompatible settings between ABP's distributed cache and the .NET JSON serializer. This typically happens after upgrading .NET or ABP versions, or when using distributed cache (e.g., Redis) with cached objects that have reference loops or require special handling.

    To resolve this in ABP 9.x:

    1. Check Distributed Cache Configuration

      • Ensure your distributed cache (e.g., Redis) is configured correctly and does not use custom or legacy serialization settings that conflict with .NET 8/9 defaults.
      • If you have custom JsonSerializerOptions, remove or update them to avoid setting both ReferenceHandler and JsonObjectCreationHandling.Populate.

    2. Clear Existing Cache

      • If the cache contains data serialized with incompatible settings from a previous version, clear your distributed cache (e.g., flush Redis). Old cache entries can cause deserialization failures after upgrades.

    3. Update ABP and .NET Packages

      • Make sure you are using compatible versions of ABP and .NET. If you are on .NET 8 or 9, use the latest ABP 9.x version and ensure all related NuGet packages are updated.

    4. Review Custom Serialization Code

      • If you have custom cache serializers or use AbpSystemTextJsonSerializer, ensure you do not set both ReferenceHandler and JsonObjectCreationHandling.Populate in your JsonSerializerOptions.

    5. Example: Correct Cache Serializer Configuration

    Configure<AbpSystemTextJsonSerializerOptions>(options =>
   {
       options.JsonSerializerOptions.ReferenceHandler = null; // or ReferenceHandler.Preserve if needed, but not with Populate
       // Do not set JsonObjectCreationHandling.Populate
   });
    1. Restart Application
      • After clearing the cache and updating configuration, restart your application.

    For more details, see:

    If the problem persists, ensure all microservices or app instances use the same ABP and .NET versions and cache configuration.
