Hi,
In our mapping we have 2 different object fields.
When we recently upgraded from Kibana 5.3.2 to 6.2.4, we lost the ability to "analyze" one of the 2 object fields.
Perhaps the screenshots better illustrate what I mean.
Beofre, on "exception" I go and filter for a specific value in the sidebar, and it wasn't shown as JSON in the table. (Instead, it was exception.name, exception.trace, etc.)
Now, it seems, something happened that prevents Kibana from indexing it. The mapping is almost the same, just different field names (Mapping JSON: https://pastebin.com/raw/82G9kRYa).
Why is "exception" not analyzed in our case, and how can we fix that?
