Hello,
I installed Metricbeat in debian server and it send all metrics to Eleasticsearch, however when I added docker module to see information about running containers and images, it works fine but I don't get any information about docker images, I checked metricbeat logs, it throws those messages:
> 2017-06-09T12:13:58+02:00 WARN Can not index event (status=400): {"type":"mapper\_parsing\_exception","reason":"object mapping for [docker.image.tags] tried to parse field [null] as object, but found a concrete value"}
Metricbeat version: 5.4.1
docker version:

Hi @sadok-f,
This looks like a bug to me, I would say we have a parsing error while retrieving image tags from the API. Could you open a new issue in our github so we can dig more on this? [https://github.com/elastic/beats/issues](https://github.com/elastic/beats/issues)
It would be awesome if you can give more details on your existing setup, specially around images, something like dumping: `docker images`

Thank you for your response,
I just created an issue on GitHub:
