Help with message structure and sharing it. (making it visible)

General

Folks, this has got me going around in circles.

I have OLD (Noah vintage) code and it is (of course) buggy.

I've put in new code to help parse the error and give me more information, but.....

It isn't working.

This is what I'm getting Oops message [object Object]
Which doesn't help.

This is the node which makes the message:

if (msg.payload == "On-line") {
    msg.payload = ({ fill: "green", text: "Online" });
} else
if (msg.payload == "Off-lineB")
{
    msg.payload = ({ fill: "yellow", text: "Offline" });
} else
if (msg.payload == "Off-lineC")
{
    msg.payload = ({ fill: "red", text: "Offline" });
} else
if (msg.payload == "Off-line") {
    msg.payload = ({ fill: "yellow", text: "Offline" });
} else
{
    msg.payload = ({fill: "blue", text: "oops"});
    node.warn("Oops message " + msg.payload);
}
return msg;

Note the node.warn line.

So - looking at it - the message is an object. Fair enough.

But I'd like to see that object so I can better understand what is going on.

This is only the first step as I have another subflow further down the line which is saying it is getting errors when it isn't and I am going to have to put in serious work to get my head around it.
I digress.

Sorry.

So what do I need to do to expand the objects so I can better see what's going on?

Thanks in advance.

Change it to...

node.warn({info: "Oops message",  payload: msg.payload});

Thanks.

I'll mention here, that that node is in a ..... (cringe) subflow too... :frowning:
I know not many people like that.

But shall do now.

Thanks.

That did work.

Alas still no progress on the bigger picture though.

Once you are using ( ... ) you are calling a function, remove them.

Thanks.

But I think it needs to be like that but with quotes in it something like:

msg.payload - ('{fill:"green", text:" Online" }')
as the fill:"green", text:"Online"} is to be used for the node.status bit further down the chain.

First you set an object:

msg.payload = { fill: "green", text: "Online" }

if you want to use that later:

node.status(msg.payload)


// if you want 'oops':
node.warn('Oops: ' + JSON.stringify(msg.payload)) 
// or as an object:
node.warn(msg.payload)

Thanks and sorry.

Been a bad day. Train network fell over and I lost a lot of time on other things.

Had to quit this morning and have kind of only just got back to it.
