Elasticsearch/Filebeat _meta/fields.yml not loading into kibana - elasticsearch

Question

I'm assigned to a filebeat plugin of our product. I wrote a IngestPipeline and de default mapping is in various ways unfortunately so i wanted to change this with the _meta/fields.yml.
I configured the yml file accordingly to:
https://www.elastic.co/guide/en/beats/devguide/7.8/filebeat-modules-devguide.html#_metafields_yml_2
https://www.elastic.co/guide/en/beats/devguide/current/event-fields-yml.html
https://github.com/elastic/kibana/issues/82273
My yml file looks like this:

I would like to have the field types as configured in the fields.yml file. But at first no mapping is available and if i start to send logs the mapping for my fields is created automatically with unfortunate types.

Answer 1

The yaml file works as it is in the description above. My Problem was that my collegue from whom i inherited the project didn't use the filebeat build script. So the uploaded fields.yml file wasn't extended by my fields. I reconfigured the fields.yaml path inside the filebeat.yml configuration file and now it works.
