sendevent@1.0.0 Generic-ish transform to dump an entire context into a sendEvent call

sendevent@1.0.0 Expression

// Merges the original context with the expected contract and then filters out the original context's properties
$ ~> | $ | 
{
    "instanceId": $.originatorId, 
    "event": "CONTINUE", 
    "context": $ ~> | $ | {}, ["originatorId"] | 
}, [
    $filter($keys($), 
        function($key) { 
            $key != "instanceId" and $key != "context" and $key != "event" 
        })
    ] 
| 

sendevent@1.0.0 Sample Context

// Renamed "instanceId" to "originatorId" as to not confuse the instanceId of the parent machine (origin) and the child machine.
{
  "originatorId": "12345",
  "tenantId": "initech"
  "firstName": "Steve",
  "phoneNumber": "+14155551212",
  /* ...whatever else you need in the payload */
}

sendevent@1.0.0 Sample Result

// {
//   "instanceId": "12345",
//   "event": "CONTINUE",
//   "context": {
//     "firstName": "Steve",
//     "phoneNumber": "+14155551212",
//     "tenantId": "initech"
//   }
// }

FYI The "function" is not a raw JavaScript function, but a JSONata evaluated function.
