What does a full line in the file you are processing look like?

The recommended way to create a config is to remove the Elasticsearch output and just output to stdout, then start with a minimal config, e.g. file input with json codec, and inspect the result. Then add filter after filter until complete, while continuously inspecting how the format of the data changes.

Once you have completed the configuration and the events look like they should, you switch from the stdout plugin to the elasticsearch plugin.
