Inject works to send to a SOAP web service but the same payload from a function doesnt?

General
1

If I wire up the inject to the purple GetChargeData it works.

If I wire up the function to the GetChargeData it does NOT work even tho the strings are the same as seen in the debug window. The top one is the inject and the bottom is the function wired in. Same payload...??

Would you give this a go (I cant test it as I dont have access to your data)

check the output of debug 1 when it is fired by the modbus node VS the inject node.

(hopefully I havent completely ruined your flow :smiley: )

Thanks you for trying! I am really stuck here. It looks like it is doing the same thing. The payload is still null in debug 2

What is that?

Does the inject route work but the modbus route not work?

5

Debug 1 payload seems to have the proper string but when I send the exact same string in with anything other than a inject, I dont get anything but null back for debug 2 payload.

It should have all sorts of data in there. I have compared the inject string and the payload string in word with formatting on. Exact same except for some spaces, which I have tried removing also.

So the only differnece I can see is that other properties are present in the msg going into the soap node. Lets rule that out.

Open the function named set msg.sn and replace all code with this...

let arr = msg.payload.data;
arr.pop();
let sn = String.fromCharCode(...arr)
return {sn:sn};

see how that performs

EDIT

Sorry your answer wasnt 100% clear please answer...

  • Did it work when clicking the INJECT called "msg.sn = BVGJ01315"?
  • Did it work when clicking the INJECT called "test envelope"?
7

Same as shown in pic with this code. Still null. I used delete msg.x to remove the stuff before when i was playing around and it didnt help either.

Yes it works with the inject msg.sn = bvg...

and yes the second inject worked also

Feed both strings into a function node containing
msg.payload = msg.payload.length
return msg
and feed into another debug node. Check the two strings give the same number.

Do the status or catch nodes show anything if linked to the soap node?

9

can you capture debug 1 and debug 2 for all 3 operations (modbus, inject1 and inject2).

click the copy button that appears under your cursor when you hover in the debug window msg and paste them in a reply

modbus - debug 1...
```
paste debug copied data
```
modbus - debug 2...
```
paste debug copied data
```

etc etc

10

Not quite sure what you want me to do. Both strings?

The catch and status never showed anything different between the two that I saw. About to call it for the day but I really appreciate the help. There is something different about the inject vs the function

Like this or am i messing up how to put the results on here

The failing one from the function node and the working one from the inject, that are supposed to be identical. Check the length to make sure there aren't any extra unprintable characters in there.

This is the problem.

In your other thread, I suggested you use buffer-parser - it takes care of all this kind of thing.

to clean up the sn you need to do soething like...

let arr = msg.payload.data;
arr.pop();
let sn = String.fromCharCode(...arr)
sn = sn.replace(/\0.*$/g,'');
return {sn:sn}
16

Note that, in the original thread, I did ask you to show us the strings in the way Steve has asked, but you ignored or did not notice that request.

BOOYAHHHHH nice work. I think that did it. I will verify more tomorrow!!!
