Description of the problem including expected versus actual behavior:
similar to #8149
Error with deserialization when using this construction.

"filtered_categories", new FiltersAggregation
                    {
                        Filters = new Buckets<Query>(categoryCodes.ToDictionary(
                                y => y, 
                                x => (Query)new TermQuery(new Field("Categories")) { Value = x }))
                    }

Here the exception
