I'm trying to define a format for my logs and these must include lists of objects. When I upload my log file to ElasticSearch, it doesn't know how to parse the lists and I don't see how to configure this.

Example NDJSON log:

```auto
{"id_of_execution":123,"branch":"master","timestamp":1628682978,"hostname":"HOST_1","full_version":"4.3.4-43bca4","known_issues_table":[{"key":1,"name":"DG-1"},{"key":2,"name":"DG-2"}]}
{"id_of_execution":125,"branch":"feature_new","timestamp":1628682979,"hostname":"HOST_1","full_version":"4.5.0-32ab03","known_issues_table":[{"key":1,"name":"DG-1"},{"key":2,"name":"DG-2"},{"key":255,"name":"DG-4"},{"key":256,"name":"DG-67"}]}
{"id_of_execution":126,"branch":"feature_new2","timestamp":1628682956,"hostname":"HOST_2","full_version":"4.6.0-32ff34","known_issues_table":[{"key":1,"name":"DG-1"},{"key":2,"name":"DG-2"},{"key":255,"name":"DG-45"},{"key":256,"name":"DG-68"}]}
{"id_of_execution":127,"branch":"feature_new3","timestamp":1628682934,"hostname":"HOST_55","full_version":"4.7.0-32cc75","known_issues_table":[{"key":1,"name":"DG-1"},{"key":2,"name":"DG-2"},{"key":255,"name":"DG-3"},{"key":256,"name":"DG-69"}]}

```

The list `known_issues_table` is recognized as of type `unknown type` and I would like this to be recognized as an object within the main object with an array. Is this possible?
