All Find queries fail after upgrade


After deploying upgraded site to production server I can see that all Find searches gives error:

System.MissingMethodException: Method not found: 'System.Collections.Generic.IEnumerator`1<Newtonsoft.Json.Linq.JToken> Newtonsoft.Json.Linq.JArray.GetEnumerator()'.
   at EPiServer.Find.ProjectionHelper.GetFieldValues(SearchRequestBody requestBody, SearchHit`1 searchHit)
   at EPiServer.Find.ProjectionHelper.GetMappedSearchResultItem[TResult](SearchRequestBody requestBody, SearchHit`1 searchHit)
   at EPiServer.Find.ProjectionHelper.GetMappedResult[TResult](SearchRequestBody requestBody, SearchResults`1 jsonResult)
   at EPiServer.Find.SearchExtensions.GetProjectedResult[TResult](ISearch`1 search, SearchContext context)
   at EPiServer.Find.SearchExtensions.GetResult[TResult](ISearch`1 search)
   at EPiServer.Find.Cms.SearchRequestExtensions.GetPagesResult[TPageData](ITypeSearch`1 search, LanguageSelector languageSelector)


The same code is working fine on local machine and on test server. I have tried re-indexing the site without no effect.

I'm running the latest EPiServer and EPiServer Find version (7.6).

The solution:

  • Make sure you run the latest EPiServer Find version
  • Remove Newtonsoft.Json from C:\Windows\Microsoft.NET\assembly\GAC_MSIL\

Thanks to Henrik Lindström for pointing me in the right direction!
