Mongo db metric set 5.5.0 log errors

[randude]

I'm getting these messages:

2017-07-24 13:01:33 +0000 /usr/share/metricbeat/bin/metricbeat[3031]: INFO - - beat.go:207: metricbeat start running.
2017-07-24 13:01:33 +0000 /usr/share/metricbeat/bin/metricbeat[3031]: ERR - - schema.go:38: Error on field 'ms': Key commits not found
2017-07-24 13:01:33 +0000 /usr/share/metricbeat/bin/metricbeat[3031]: ERR - - schema.go:38: Error on field 'ms': Key commitsInWriteLock not found
2017-07-24 13:01:33 +0000 /usr/share/metricbeat/bin/metricbeat[3031]: ERR - - mapstriface.go:78: Error accessing sub-dictionary storageEngine

My yaml field is rather simple:

metricbeat.modules:

• module: system
  metricsets:

  • cpu
  • load
  • diskio
  • filesystem
  • fsstat
  • memory
  • network
  • process
  • socket
    enabled: true
    period: 10s
    processes: ['.*']

• module: mongodb
  metricsets: ["status"]
  enabled: true
  period: 10s
  hosts: ["localhost:27017"]

output.logstash:
hosts: ["localhost:5044"]
compression_level: 0
ssl.enabled: false

logging.to_files: true
logging.files:
path: /var/log/metricbeat
name: metricbeat
rotateeverybytes: 10485760
keepfiles: 7

Any help is welcomed.
Thanks.
