Point in json path in flattenSpec

Hi guys,

Trying to ingest some json data.
I have some nested fields that contain a point in field name - “ccaud.x”. So, the path is something like $->query->ccaud.x

I’m trying this:


but it does not seem to work.

Any idea how i could configure/ingest that?

Thanks, Vadim.

What is the error you see?
