huxi opened a new issue #1648: Result contains "offset": null instead of "offset": 0
URL: https://github.com/apache/couchdb/issues/1648
 
 
   <!--- Provide a general summary of the issue in the Title above -->
   A query with a `keys` argument, `_all_docs?include_docs=true&keys=["key"]`, suddenly returns `"offset": null` instead of `"offset": 0`.
   
   Performing the same query without the `keys` argument, i.e. just `_all_docs?include_docs=true` returns a correct offset of `0`.
   
   ## Expected Behavior
   <!--- If you're describing a bug, tell us what should happen -->
   ```json
   {
     "total_rows": 64,
     "offset": 0,
     "rows": [
       {
         // the result rows
       }
     ]
   }
   ```
   
   <!--- If you're suggesting a change/improvement, tell us how it should work -->
   
   ## Current Behavior
   <!--- If describing a bug, tell us what happens instead of the expected behavior -->
   ```json
   {
     "total_rows": 64,
     "offset": null,
     "rows": [
       {
         // the result rows
       }
     ]
   }
   ```
   <!--- If suggesting a change/improvement, explain the difference from current behavior -->
   
   ## Context
   <!--- How has this issue affected you? What are you trying to accomplish? -->
   The issue started showing up after upgrading a CouchDB cluster from 2.1.0 to 2.2.0.
   
   It causes a `JsonParseException` in [QueryResultParser](https://github.com/helun/Ektorp/blob/master/org.ektorp/src/main/java/org/ektorp/impl/QueryResultParser.java#L75) of [Ektorp](https://github.com/helun/Ektorp).
   <!--- Providing context helps us come up with a solution that is most useful in the real world -->
   
   ## Your Environment
   <!--- Include as many relevant details about the environment you experienced the bug in -->
   * Version used: 2.2.0
