One of the results you will find if you search your sitecore solution for one of the params (i.e. facetsRootItemId) is App_Config\Sitecore\SPEAK\Sitecore.Speak.ItemWebApi.config
You can use this file to find which processor deals with the search request, which is Sitecore.ItemWebApi.Pipelines.Request.Search, Sitecore.Speak.ItemWebApi.
What I suggest is overriding that processor, using the code from the decompiled DLL. Then stick a break point in the code and see if and where any of the OTB code is failing, this should help you diagnose further the issue.
Example code below:
using Sitecore.ContentSearch;
using Sitecore.ContentSearch.Linq;
using Sitecore.Data;
using Sitecore.Data.Items;
using Sitecore.Diagnostics;
using Sitecore.Globalization;
using Sitecore.ItemWebApi.Facets;
