2020-10-30T08:58:35.626+0000	Failed: rocketchat.assets.chunks: error creating indexes for rocketchat.assets.chunks: createIndex error: The field 'w' is not valid for an index specification. Specification: { name: "files_id_1_n_1", ns: "rocketchat.assets.chunks", w: 1, key: { files_id: 1, n: 1 } }

ERROR: The Compose file './docker-compose.yml' is invalid because:
Invalid top-level property "hubot". Valid top-level sections for this Compose file are: version, services, networks, volumes, and extensions starting with "x-".

You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
