@effapp I am guessing you are using the latest preview. Correct?

Please share the Widget-ContentFeedByTaxonomy.cshtml code. and your parts.

I am guessing in your entity.Add("key", obj) instead of entity["key"] = obj which is causing the exception. I just want to be sure it is not OC code that is causing this issue.

Hi @MikeAlhayek ,

I am using release 1.8.4 of OC.

It can execute correctly while replacing from lucene index and query to ElasticSearch index and query.

A pieces of code as follows:

var queryParams = new Dictionary<string, object>() { { "size", fetchCount }, { "from", from } };
if (!string.IsNullOrEmpty(categoryId))
{
queryParams["CategoryId"] = categoryId; // the error is same while using queryParams.Add("CategoryId", categoryId);
}
string query = (string)Model.ContentItem.Content.ContentFeedByTaxonomy.Items.Value;
var items = await Orchard.ContentQueryAsync(query, queryParams);

@effapp

queryParams["CategoryId"] = categoryId;

There this isn't the line that is causing the exception. Are
You able to reproduce this using OC branch? I would start there so you can understand the cause of the issue.

Another thing to try, is to try upgrading to OC 2.0 preview and see if you encounter the same issue. In 2.0 Newtonsoft.Json was removed from OC and YesSql.

But there is not the issue in index and query of ElasticSearch, still using Newtonsoft.Json.

The lucene query can execute correctly in admin UI but throw exception by calling code : "var items = await Orchard.ContentQueryAsync(query, queryParams);"

the code "var items = await Orchard.ContentQueryAsync(query, queryParams);" is correctly in elasticsearch query.

The cause of issue has been identified: deleting "filter:[]" from query scripts is normal.
