Trying to use jsonata to reduce array of objects. Test data works OK but fails when deployed

[colj]

Just started using node red. Have spent hours trying to get this to work! I have an array of objects which have entries for the next 72 hours ( JSON data from Solcast for PV forecasting) I'm only interested in tomorrows so using jsonata to just pick out those using the date. I have used test data in the node (copied from debug) and all looks fine. However, when I deploy and execute the node it always returns an empty object. Hopefully the screen shot shows the details, but the jsonata is:
{
"tomorrows PV forecast" :
msg.* [
$contains(
period_end,
$fromMillis(
$millis()+10006060*24,
'[Y0001]-[M01]-[D01]'
)
)
]
}

I suspect your test data is wrong
it should be

{
  "payload":{
    Your test data.
    }
}

thank you - i had just copied the object from the debug panel!
