Here:

      if (bucket_status.state != BucketSyncState::Incremental ||
          bucket_stopped) { 
        // if state is Init or Stopped, we query the remote RGW for ther state
        yield call(new RGWReadRemoteBucketIndexLogInfoCR(sc, sync_pair.dest_bucket, &info));
        if (retcode < 0) {
          return set_cr_error(retcode);
        }

It doesn't make sense to fetch the dest_bucket info when accessing the source, need source_bucket info.
