How to build custom input data from reply in ActionDataFilter

[psmdeoliveira]

Considering this reply from an application

{ "data": { "Data": { "COEreply": { "tunnel": [ { "admin-state": "UP", "endpoint": "10.255.0.149", "headend": "10.255.0.151", "oper-state": "ACTIVE", "tunnel-details": { "binding-label": 24036, "delegated-pce": "192.168.101.155", "hold-priority": 7, "non-delegated-pces": [ "192.168.101.156" ], "path": [ { "computed-time": "1695926543", "constraints": { "affinity": { "exclude-any": 0, "include-all": 0, "include-any": 0 } }, "ero-hop": [ { "index": 1, "interface-name": "FourHundredGigE0/0/0/3", "ip-address": "10.0.0.62", "node-id": "agg3", "te-hop-type": "strict" }, { "index": 2, "interface-name": "FourHundredGigE0/0/0/1", "ip-address": "10.0.0.30", "node-id": "c1", "te-hop-type": "strict" }, { "index": 3, "interface-name": "FourHundredGigE0/0/0/0", "ip-address": "10.0.0.114", "node-id": "agg1", "te-hop-type": "strict" }, { "index": 4, "interface-name": "FourHundredGigE0/0/0/3", "ip-address": "10.0.0.53", "node-id": "pe1", "te-hop-type": "strict" } ], "optimization-metric": { "metric-type": "DELAY", "metric-value": 120 }, "path-name": "123", "path-oper-state": "ACTIVE", "path-type": "PT-UNKNOWN" } ], "pcc-address": "10.255.1.151", "pcep-info": { "pcep-flag-c": 0 }, "setup-priority": 7, "signaled-bandwidth-mbps": "0", "update-time": "1695926551068" }, "tunnel-id": 123 } ] } } } }
For the next step in the workflow I need to extract the "ero-hop.ip-address" into an array
Like this:
["10.0.0.62","10.0.0.30","10.0.0.114","10.0.0.53"]

With a Jinja template this is easy to create... but how can I do this using the Serverless Workflow Specification?

"actionDataFilter": { "results": "${ if (.data) then ??? jinga / function ??? | fromjson else {\"detail\":\"not found\"} end }", "toStateData": "${ .EROHopArray }" }

Done!

      "actionDataFilter": {
        "results": "${ if (.data) then .data | fromjson.\"rsvp-te-tunnel\"[0].\"tunnel-details\".path[0].\"ero-hop\" | map(.\"ip-address\") | tojson else null end }",
        "toStateData": "${ .reply }"
      }
