Hi @amitsa , what is the command line invocation you are using for Rally? I double-checked, and this is fixed in the version of nyc\_taxis that is compatible with 8.2: [rally-tracks/index.json at 8 · elastic/rally-tracks · GitHub](https://github.com/elastic/rally-tracks/blob/8/nyc_taxis/index.json) (no `_source.mode` setting) ---

Ah ok, As we mentioned in the original post, the problem is not in Rally but in the upstream rally-tracks repository that it depends on. When you use `--offline` it does not fetch track updates from remote track repositories. ---

How to make it work in offline mode? any workaround? ---

The branch `master` should not be used for compatibility reasons. See [Track Reference - Rally 2.7.0 documentation](https://esrally.readthedocs.io/en/stable/track.html?highlight=branch#custom-track-repositories) For 8.2 please use download.sh while branch `8` is checked out in git ---

Does using es version 8.4 or greater than 8.4 can help? i am not using any distribution version in cli. I am just downloading track data from master using download script. ./download.sh nyc\_taxis ---

Apologies, it's not download.sh that is concerning, it's the version of the track. `--track-path=/rally/.rally/benchmarks/tracks/default/${ES_RALLY_RACE}` is pointing to a version of the track that doesn't work. > The branch `master` should not be used for compatibility reasons. See [Track Reference - Rally 2.7.0 documentation](https://esrally.readthedocs.io/en/stable/track.html?highlight=branch#custom-track-repositories) Therefore you should check out branch `8` at that location. Using version 8.4 will technically get you over this specific error but won't guarantee that you are using a version of the track that we have tested or asserts works with your stack version, because you are not using an intentional version of the benchmark code. ---

No, unfortunately. Therefore you should check out branch `8` at that location. ---
