No I meant the value of the msg object from your debug output.

Property comparison weirdness

gentle barn Aug 18, 2024, 3:17 PM

#

The msg object from your example or from my implementation? The above copy is from my implementation

spring apex Aug 18, 2024, 3:17 PM

#

From yours. I know mine works.

gentle barn Aug 18, 2024, 3:17 PM

#

Is that not what I have shared?

#

Sorry if that's stupid

spring apex Aug 18, 2024, 3:18 PM

#

Oh. It looked like a Node Red export. Maybe I'm the stupid one 😄

#

Okay import that: https://dpaste.org/pAGLC/raw
I replaces the whole msg object with your output and it still works fine here.

gentle barn Aug 18, 2024, 3:22 PM

#

Okay, amazing, that definitely works

#

I don't really understand why though...

spring apex Aug 18, 2024, 3:23 PM

#

Me neither.

#

But it's definitely not because of an array.

gentle barn Aug 18, 2024, 3:23 PM

#

Interesting

#

Is that function actually changing anything?

spring apex Aug 18, 2024, 3:24 PM

#

I modified it to have a debug output: #1274748148669222933 message

#

But it basically replaces the whole msg with what you had so I can test it over and over again exactly as if I had your input.

gentle barn Aug 18, 2024, 3:26 PM

#

I'm a little confused about what to try now, seeing as the exact same msg works from a function

#

hang on, now if I skip the function it's working

#

Sorry no ignore me

spring apex Aug 18, 2024, 3:27 PM

#

I'd try without JSONata.

gentle barn Aug 18, 2024, 3:29 PM

#

My message comes from a plugin node, I don't really have any control over it 😥

spring apex Aug 18, 2024, 3:31 PM

#

Your change node uses JSONata.

gentle barn Aug 18, 2024, 3:31 PM

#

I'm not even using a change node now, it's literally this

spring apex Aug 18, 2024, 3:32 PM

#

Add a whole msg debug node after the discord node. Then please share the flow and the debug's output.

gentle barn Aug 18, 2024, 3:33 PM

I'm pretty sure this will be identical bar some timestamps to what you put into the function

spring apex Aug 18, 2024, 3:37 PM

#

Hmm. All I did was replacing the discord node. Funky: https://dpaste.org/rN5kH/raw

gentle barn Aug 18, 2024, 3:38 PM

#

The weird thing is I can definitely write conditions on the member.displayName value, which is obviously not within an array

#

That's why I think it's an array thing

#

Perhaps there's a special character that is not going in the function but is persisting from the discord node?

spring apex Aug 18, 2024, 3:38 PM

#

Makes no sense through if my flows work fine for you and do exactly the same.

#

That was my thought and why I wanted the output.

gentle barn Aug 18, 2024, 3:40 PM

#

spring apex Hmm. All I did was replacing the discord node. Funky: https://dpaste.org/rN5kH/r...

Again this works for me

#

It's gotta be something to do with the Discord node, and somehow not impacting all values

spring apex Aug 18, 2024, 3:42 PM

#

Let's try something really simple then. Add this node after your discord node

[{"id":"4464cb801fe3c9f7","type":"function","z":"cae8eceb71b2cae3","name":"Check for msg.memberRoleNames[0].name","func":"node.warn(`msg.memberRoleNames[0].name: \"${msg.memberRoleNames[0].name}\"`);\n\nif (msg.memberRoleNames[0].name == \"HomeController\") {\n    node.warn(`HomeController found`);\n} else {\n    node.warn(`HomeController not found`);\n}\n\nreturn msg;","outputs":1,"timeout":0,"noerr":0,"initialize":"","finalize":"","libs":[],"x":490,"y":380,"wires":[[]]}]

gentle barn Aug 18, 2024, 3:43 PM

#

TypeError: Cannot read properties of undefined (reading 'name')

spring apex Aug 18, 2024, 3:43 PM

#

Interesting.

#

gentle barn Aug 18, 2024, 3:45 PM

#

spring apex Aug 18, 2024, 3:45 PM

#

Try this variant

[{"id":"58ee766f8c876f10","type":"function","z":"cae8eceb71b2cae3","name":"Check for msg.memberRoleNames[0].name","func":"node.warn(msg);\nnode.warn(`msg.memberRoleNames[0].name: \"${msg.memberRoleNames[0].name}\"`);\n\nif (msg.memberRoleNames[0].name == \"HomeController\") {\n    node.warn(`HomeController found`);\n} else {\n    node.warn(`HomeController not found`);\n}\n\nreturn msg;","outputs":1,"timeout":0,"noerr":0,"initialize":"","finalize":"","libs":[],"x":710,"y":280,"wires":[[]]}]

gentle barn Aug 18, 2024, 3:46 PM

#

spring apex Aug 18, 2024, 3:46 PM

#

Can you expand the warn object.

gentle barn Aug 18, 2024, 3:47 PM

#

It looks like a copy of the normal message

#

spring apex Aug 18, 2024, 3:48 PM

#

I don't really understand what's happening here.

gentle barn Aug 18, 2024, 3:48 PM

#

I'm glad I'm not the only one

#

There's clearly something going on outside of the message

spring apex Aug 18, 2024, 3:48 PM

#

But maybe these tests still helped somewhat.

gentle barn Aug 18, 2024, 3:51 PM

#

Is there a method to convert a whole object into a string and then try a compare on that?

#

It's almost 2am on a work night so I'm going to come back to this another time, maybe after a version upgrade. I'm not awfully hopeful that it'll change anything but you never know :D

#

Thanks for your help @spring apex , really appreciate it

spring apex Aug 18, 2024, 3:53 PM

#

Not directly. It would be a mess to convert JSON to a single string, no?

#

There's a JSON node though to convert objects to JSON and JSON.stringify for the function node.

gentle barn Aug 18, 2024, 3:54 PM

#

spring apex Not directly. It would be a mess to convert JSON to a single string, no?

Sure, but it seems to only fail with array values. It would at least help understand it better

gentle barn Aug 18, 2024, 3:57 PM

#

spring apex There's a JSON node though to convert objects to JSON and `JSON.stringify` for t...

the json node made it work

#

#

Clearly it's a pretty shit solution but at least now nodered can find the value I'm looking for

#

On the plus side it's potential future proofing, ensuring that it checks all items in the array, which covers me in case they change order

spring apex Aug 18, 2024, 4:01 PM

#

You can do this via JSONata too with something like

[$contains(name, "HomeController")]

Not very trivial though and I already forgot most of JSONata's syntax.

gentle barn Aug 18, 2024, 4:01 PM

#

Sorry for another dumb question - what node should this be in?

spring apex Aug 18, 2024, 4:02 PM

#

Whatever you want. In my case I use a change node to extract it.

gentle barn Aug 18, 2024, 4:02 PM

#

This is my first Nodered project so my brain is empty

spring apex Aug 18, 2024, 4:02 PM

#

I use this to extract power plugs and other things from my Zigbee2MQTT's devices message.

#

It's a big hack so I can reconfigure their reporting interval which gets reset sometimes. To do this I need to extract their names and this is what I came up with since they all share a prefix.

gentle barn Aug 18, 2024, 4:04 PM

#

spring apex You can do this via JSONata too with something like ```javascript [$contains(nam...

This works directly in the switch

#

I think that's a cleaner solution

#

One less node at least

spring apex Aug 18, 2024, 4:04 PM

#

I hate that I don't know what causes this weird behavior though.
