Metricbeat fails to index docker metadata


I have deployed Metricbeat and Auditbeat (7.1.0-SNAPSHOT) as a daemonSet on a k8s cluster, the container Metricbeat module is reporting the info of an event related to Auditbeat daemonSet and it fails to store the data on Elasticsearch with a mapping error

"org.elasticsearch.index.mapper.MapperParsingException: failed to parse field [docker.container.ip_addresses] of type [ip] in document with id '4ARYWWkBTidYNB1MYom3'","at org.elasticsearch.index.mapper.FieldMapper.parse( ~[elasticsearch-7.1.0-SNAPSHOT.jar:7.1.0-SNAPSHOT]","at 

This is the JSON message, the IP is empty so it is not an IP ("ip_addresses": [""],), as a workaround I have disabled the containers module on the docker.yml file.
