  Tested locally with the code snippet

void ShardMap::list_shards(const Aws::String& next_token) {
  Aws::Kinesis::Model::ListShardsRequest req;
  req.SetMaxResults(1);

  if (!next_token.empty()) {
    LOG(info) << "[DEBUG] Updating shard map for stream \"" << stream_ << "\", the max result has been set to 1";
    req.SetNextToken(next_token);
  } else {
...
  }

and verified that the next page of shards can be successfully loaded:
