Bug in haproxy example config

[defcon84]

If I use the default haproxy.d/conf.yaml.example the integration returns an exception:

Datadog’s haproxy integration is reporting:
Instance #initialization[ERROR]: yaml: unmarshal errors: line 3: cannot unmarshal !!map into []integration.RawMap

It seems Instances is a list and the default dash (-) on row 48 was removed in this changeset:

this is the (condensed) current, wrong example config:

init_config:
instances:

This is what it should be:

init_config:
instances:
  -

@defcon84 when is it useful to have an empty instances field?

@defcon84 when is it useful to have an empty instances field?

In the Haproxy specific, I don't know if an empty instance field is useful.
This is the config I use now:

init_config:
instances:
  -
    use_openmetrics: true
    openmetrics_endpoint: http://10.x.x.x:8404/metrics

But the - is needed or it throws an exception.

Also, it would be more in line with the other example config files, eg:
