I have JSON documents that I send through a lambda to Elasticsearch and these JSONs have certain fields nested that are flattened in the process, I can see that they are correctly showed in my Index Pattern, like this:
But when I go to discover, the only field that is correctly showing is the one that ES mapped as a date field:
I have already checked that the documents that I sent to ES through the lambda have values inside these fields. But these fields don't appear in Discover, like the image above and when I expand a single document, I can't see these fields too (even when I uncheck "hide missing fields").
Thanks in advance for any suggestion.
