[Metricbeat] consumer_utilisation issue with RabbitMQ module in 7.0.0

[sygnowskip]

Hi,
after update of Metricbeat from version 6.6.2 to 7.0.0 module for RabbitMQ monitoring is not working.

I'm receiving following errors (multiple):
1 error: wrong format in "consumer_utilisation": expected integer, found <nil>;

Configuration for rabbitmq.yml:

- module: rabbitmq
  metricsets: ["queue"]
  enabled: true
  period: 180s
  hosts: ["localhost:15672"]
  fields.beattype: "rabbit"

I've verified it and RabbitMQ is returing consumer_utilisation as null, but version 6.6.2 is able to parse it correctly, but 7.0.0 is throwing an error.

Is it expected behavior? Should I change something in configuration?

Same issue here.
The used schema for the object received by from the RabbitMQ management API did not change.
https://github.com/elastic/beats/blob/v6.6.2/metricbeat/module/rabbitmq/queue/data.go

Maybe the implementation of schema
or one of the helpers in mapstriface did change.

Update

The plugin still works fine in 6.7.1 too.
Also there are no changes in schema.go and mapstriface.go from the 6.7 branch to master.
The issue must be located somewhere else.

I'm trying to reproduce the issue, no luck so far.
I guess the reason is that I'm not receiving the field, vs receiving it with no data.
Is that your case?
