wrong number of arguments (given 0, expected 1)

Hello,

I have unit tests that are working perfectly with logstash 7.17. When upgrading to 8.10, all the tests fail with the following error:

An error occurred while loading ./spec/05_logstash_squid_service_prd_spec.rb.
Failure/Error:
  sample('message' => message, 'type' => 'logs-systems', 'logStream' => 'logs-squid-service-prd/service/b99b3b857c8148b19bc73bc8b85aaba4', '@timestamp' => LogStash::Timestamp.coerce('2020-01-14T11:35:54.795Z')) do # <2>
    # Check the ouput event/message properties
    insist { subject.class } == LogStash::Event # <3>
    insist { subject.get('type') } == 'logs-systems'
    insist { subject.get('@timestamp').to_iso8601 } == '2020-02-26T11:47:08.467Z'
    insist { subject.get('system') } == 'squid'

    insist { subject.get('url') } == 'http://app.abc.com/api/abc'
    insist { subject.get('cache_result') } == 'TCP_MISS'

ArgumentError:

Here is the content of the spec:

    expect(subject.get('tags').include?('_grokparsefailure')).to be_falsey
    expect(subject.get('tags').include?('_dateparsefailure')).to be_falsey
  end
end

What can be the reason for this?

Thanks
