SugandhaAgrawal opened a new pull request #4388: Adapt limit to query db view 
as per couch db change
URL: https://github.com/apache/incubator-openwhisk/pull/4388
 
 
   Co-authored-by: steffenrost <[email protected]>
   
   CouchDB has introduced a limit check for querying the database view, for the 
query parameter `limit`. In OpenWhisk it was first set to Scala `Int.Max` 
value. Since this exceeds the allowed range by couchDB, the query calls using 
the max value have been reported failing with `http Response: 400 Bad Request`.
