Before .NET 8 setting global settings in an Azure Function used to work just fine. Now this same code doesn’t work in .NET 8 and Azure Functions v4:

        // Setting global System.Text.Json.JsonSerializerOptions
        services.Configure<JsonSerializerOptions>(options =>
        {
            options.PropertyNameCaseInsensitive = true;
            options.DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingDefault;  // Property is ignored if its value is null. This is applied only to reference-type properties and fields.
        });

Is this no longer supported? I cannot find any documentation how to do it in .NET 8.
