Using $moment() in change node jsonata 'Test' results in an error

[zenofmud]

In the change node, if you are using JSONata and use the $moment() function and try to test it, you get an error

Error evaluating expression:
  Attempted to invoke a non-function

Bug (?) or is this just something you can't use in the 'Test' portion?

What I want to do is deal with an object in this format:

[
    {
        "time": 1608813423311,
        "humidity": 36.7
    },
    {
        "time": 1608813423511,
        "humidity": 35.5
    }
]

and return the times as hh:mm am/pm

Hi
try

payload ~> |[*]|{"time":$moment(time).tz("london/europe").format("hh:mm a")}|

@zenofmud

just something you can't use in the 'Test' portion?

That's it... We don't have the moment library loaded in the editor, so just like the context functions, you can't use it in the test panel

Should probably have a message display as we do for the context functions.

@E1cid thanks for the effort but that gives me a
"Invalid JSONata expression: Argument 1 of function undefined does not match function signature"
message. I'm just going to use a function so I'll be able to understand it in the future

Strange, as working here

Try this flow

[{"id":"4c8fe74d.23b62","type":"inject","z":"8d22ae29.7df6d","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[     {         \"time\": 1608813423311,         \"humidity\": 36.7     },     {         \"time\": 1608813423511,         \"humidity\": 35.5     } ]","payloadType":"json","x":160,"y":2380,"wires":[["6040a378.a42784","84c9d74a.048ca8"]]},{"id":"6040a378.a42784","type":"change","z":"8d22ae29.7df6d","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"payload ~> |[*]|{\"time\":$moment(time).tz(\"london/europe\").format(\"hh:mm a\")}|\t\t","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":370,"y":2380,"wires":[["84c9d74a.048ca8"]]},{"id":"84c9d74a.048ca8","type":"debug","z":"8d22ae29.7df6d","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":520,"y":2280,"wires":[]}]

My bad, I put it in the wrong place in my flow after a csv node. it works great!
