Research direction
Examine the HttpSourceReader.java file around lines 406-407 to understand the current cursor based pagination logic. Determine if the condition `Strings.isNullOrEmpty(newCursor)` is sufficient to detect end of data. Consider adding a check for the number of returned items being less than batchSize to handle cases where the server returns the same cursor even after data is exhausted.
