hello I am using esrally eql track to test ES7.5.1 But I met an error ,does anyone has any idea? [ERROR] Cannot race. Error in load generator [4] ("Request returned an error. Error type: transport, Description: illegal\_argument\_exception ({'error': {'root\_cause': [{'type': 'illegal\_argument\_exception', 'reason': 'Rejecting mapping update to [endgame-4.28.2-000001] as the final mapping would have more than 1 type: [\_doc, \_eql]'}], 'type': 'illegal\_argument\_exception', 'reason': 'Rejecting mapping update to [endgame-4.28.2-000001] as the final mapping would have more than 1 type: [\_doc, \_eql]'}, 'status': 400})", None) ---

This track will only work with Elasticsearch 7.10+ (see [https://github.com/elastic/rally-tracks/pull/140#issuecomment-726136641](https://github.com/elastic/rally-tracks/pull/140#issuecomment-726136641)) You will also need the plugin `mapper-size` to be installed. cc @matriv ---

@alittlejoy And as @dliappis already mentioned, please don't forget to install the mapper-size plugin, `--elasticsearch-plugins="mapper-size"` ---
