Sorry folks:
..... I'm ba-ack.....!
I've recently been working on a subflow and made a lot of silly mistakes.
(I'll cop that.)
So entered the command correctly and all should be good - yeah?
Nah.
One machine it works, the other machine, doesn't.
Details:
NR 3.0.2
node -v 16.20.02
both machines.
So what's going on?
The error I get is:
{"message":"Invalid JSONata expression: Cannot read properties of undefined (reading 'startsWith')","source":{"id":"da42a7e9064de621","type":"change","name":"#1","count":1}}
What throws me is:
undefined (reading 'startsWith')
It is a change node.
(code)

There's no startingwith( ) in there.
So I'm guessing it is a syntactical problem.
For the sake of sharing:
The code - no GUI stuff or MQTT nodes.
But the guts of the code:

On machine 1 I press the inject and the subflow works.
On machine 2 I press the inject and get the error.
Note:
the node-status changes on the faulty machine though. So all is good to there.
P.P.S
If I change that change node to this:
[

No error.
P.P.P.S.
Just checked.
the change node on both machines: same version.
3.0.2
Sorry folks, I seem to be missing something.
