Preflight TestAnalyse regex is not working well

[camilamacedo86]

Bug Description

By using Preflight to check the result of a curl it is not working well

Expected Behavior

Passed on the check when found the value.

Steps To Reproduce

• Install kurl: curl https://kurl.sh/latest | sudo bash
• Install Preflight curl https://krew.sh/preflight | bash
• Run the following check

apiVersion: troubleshoot.sh/v1beta2
kind: Preflight
metadata:
  name: kurl-builtin-oncluster
spec:
  collectors:
    - clusterResources: {}
    - run:
        collectorName: test
        image: busybox:1
        key: test
        command: [ "curl" ]
        args: ["-k", "https://localhost:6443/healthz?verbose"]
  analyzers:
    - textAnalyze:
        checkName: Kubernetes API health check
        key: test
        regex: ".*passed*"
        outcomes:
          - fail:
              when: "false"
              message: "Kubernetes API health check did not pass. One or more components are not working."
          - pass:
              when: "true"
              message: "Kubernetes API health check passed"

See that I expected that it does not Fail since I can found healthz check passed:
