Uibuilder not communicating with the Node-RED

nerevar · 12 April 2023 10:24

Hello,

I'm afraid this is gonna be very noob question, but I'm gonna ask anyway.

It's been a while when I worked with uibuilder in the way I need the node-RED to send him messages. Last time on my home PC it worked ok. Now It doesnt work at all. I've tried several index.js files but to no avail.

Anyways, this is the basic flow where uibuilder doesn not get messages from Node-RED, not does he send any. I have no idea why..

Template: VueJS & bootstrap-vue

Hi, you haven't included the uibuilder startup in that log so I can't see what version you are using. I can see that you are using an older version of Node-RED.

You also don't need a uib-sender node if you are sending direct to the uibuilder node.

Finally, if you are using Vue, you need to share your front-end code as well because the flow on its own doesn't let me see how you are using the data. Also, if using bootstrap-vue, you need to verify that you are using Vue v2.

You should also check your browsers devtools for the page to see if there are any errors.

^^ this is some old instance which I've properly deleted from node-red and folder but for some reason it wont get away from uibuilder.

TotallyInformation · 12 April 2023 11:49

Nice that you are now using the latest version and I can see that you've updated Node-RED as well.

Those are errors in Node-RED - from the Editor. You need to look at errors on your resulting web page. The first of those seems to be a Node-RED error.

Clearly something odd has happened. The error is suggesting that the namespace is wrong. That would normally be an incorrect uibuilder.start(...) in your custom front-end code but as you've said you don't have any, I think this will be related to something not being cleared out correctly.

If you haven't got any custom front-end code, I think I would recommend that you delete the uibuilder node, redeploy then add a new node, set the url and deploy.

Once you switch to the latest version of the Vue2/bootstrap-vue template, you will see that it no longer includes the panel that shows the latest received. With the newer templates and the new client, you can turn on/off the received msg panel. The following inject node will do that for you:

[{"id":"6f03e61c79a341f3","type":"inject","z":"3d1d77d64d7cd2b3","name":"showMsg","props":[{"p":"_uib","v":"{ \"command\": \"showMsg\" }","vt":"json"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":240,"y":60,"wires":[["4f5927a48643d688"]]}]

nerevar · 12 April 2023 12:14

I deleted this uibuilder node ages ago. I do have, however, over 20 nodes for testing purposes in my flows. Maybe some of them have got uibuilder.start(...) messed up?

Sure, but on my new project I like to have this panel for debugging purposes.
I'm not receiving messages on any of my instances

TotallyInformation · 12 April 2023 13:37

Shouldn't matter. All uibuilder instances are deliberately independent. So one cannot impact another.

I also have many uibuilder nodes and flows on my test system.

The error you shared:

uibuilderfe.min.js:1 [uibuilderfe:ioSetup:connect_error] SOCKET CONNECT ERROR - Namespace: /uibuilder_simple_testing, ioPath: /uibuilder/vendor/socket.io, Reason: Invalid namespace Error: Invalid namespace

Says that /uibuilder_simple_testing is an invalid namespace - but that namespace is different to the original flow you shared which was /retest. So are you sure that you had the right URL open?

You can simply add uibuilder.showMsg() to your front end js code or send the command when a client connects - either by wiring up a change node to the "client connect" control msg and feeding back to the uibuilder input or by using a cache node (similarly connected to the control output but you don't need to filter the messages).

So plenty of choice. Happy to share more code if you need it.

Right, so what errors are you getting from another of the web pages?

More importantly, what happens if you import the "templates" example and deploy it - which of those example instances work? Any of them?

nerevar · 12 April 2023 18:28

None of the templates work either.

Anyways, on my home PC everything works fine:

Thank you for the effort.

And then loading default uibuiilder template "Simple VueJS v2", I am already getting this error on the console:

Don't know if matters, but for every library I addded to uibuilder I got this message in the CMD terminal:

13 Apr 08:43:44 - [info] [uibuilder:UibPackages:npmInstallPackage] npm output:
 npm WARN config production Use `--omit=dev` instead.

Right, so now I've inserted files from my project and guess what. It is the same as before: no communication whatsoever. Also, I see the same error as before even though its a fresh install:

Which is.... frustrating as the folder .node-red was deleted and PC was restarted.
Here is what's inside the folder right now:

Did I had to install NodeJS additional tools (Python, build tools and Chocolatery)?

UnborN · 13 April 2023 07:35

as @TotallyInformation said you need to share the actual code (index.html, .js files) in order to investigate

what i notice is that in the error it says Namespace: /uibuilder_simple_testing that should be the url set in the uibuilder node ? but based on your folder screenshot, no folder uibuilder_simple_testing exists which means you dont have a matching node with that namespace. check in you code to see if you manually doing a uibuilder.start() with that namespace that doesnt exist.

nerevar · 13 April 2023 08:14

I did already and can't find a problem, anyways here are codes:

Code for node which produces this error:

As I said, standard template:

Again, at my home PC there are apsolutely no problems with any of my instances - how could it then matter what is in these files?

P.S. Couldn't insert all files because of this error: An error occurred: Body is limited to 32000 characters; you entered 72097.

Hello,

It's solved. I deleted all data from a browser.
Aparently there were some cookies leftovers.

TotallyInformation · 13 April 2023 10:51

Glad you've resolved it.

The code you've shared is still "old" style however. It will certainly continue to work but you will eventually want to bring it up to the latest approach so that you will be able to leverage the latest features.

Do check out the built-in examples now that you are on the latest versions of uibuilder and node-red. And I'm generally around in the forum so feel free to ask more questions if you get stuck.

nerevar · 13 April 2023 11:10

I know - I've saved the .js file in the project so I can study what's new for later.

Atm I'm trying to figure in which software to convert this old autocad layout to a SVG so I "modernise" the looks a bit using your "uibuilder+svg+vue.js" example. But, thats for another topic

TotallyInformation · 13 April 2023 11:56

Cool. Look forward to hearing about that, sounds interesting.

Just to note that the low-code features of uibuilder now fully support building SVG's dynamically - you can use that both from Node-RED and in front-end code.

So Vue might not be needed - though obviously if you are already familiar with it, its fine to use and can help with more complex front-end code.
