JSONata is true but switch node will not pass msg through

General
1

Hi -

I'm new to Node-RED and am trying to use JSONata in a Switch node to route my msg.payload. I found this in my search and attempted to replicate it for my data. Though the JSONata Test reports True, my payload goes no further. The JSON is a vm_info including tags created by Ansible..

My attempt to replicate the example in the linked post with JSONata in the Property field:

true in tags[*].$contains($.name, "AnsibleManaged")

ref: JSONata Exerciser

Additionally, I have tried the following syntax as a JSONata rule:

"AnsibleManaged" in tags.name

ref: JSONata Exerciser

and

true in tags[*].$contains($.name, "AnsibleManaged")

... these both evaluate to True and pass the test against my JSON.

I'm obviously not doing something correctly here and would appreciate any help. Thanks!

Your array is in payload.tags

p.s. Love the full info and examples provided

[edit]
Your jsonata exerciser is missing the payload element to

    "uuid": "4207b810-fc10-a2ad-dd5d-ced4ba83d953",
    "vm_network": {
      "00:50:56:87:bc:74": {
        "ipv4": [
          "192.168.50.254"
        ],
        "ipv6": [
          "fe80::250:54ff:fe87:bc74"
        ]
      }
    }
  }
}
