I tried 2 example programs from the IBM website.
timestamp example
I cannot see anything in the debug tab. Debug node is of course activated and its output is set to debug tab and console.
Chrome developer tools gives some more information:
Warning: SVG's SMIL animations (, , etc.) are deprecated and will be removed. Please use CSS animations or Web animations instead.
It also detects that something has happended (Preview "OK", Response "OK").
I also tried Chat example
But even when I try to execute the "Run the app" button the window never displays "connection established" or any chat message. Chrome developer tools throws error:
Uncaught InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.
I did not install anything related to Java, JS, JSON, Node.js on my pc as I asume that everything runs inside Bluemix.
The underlying issue is a failure to establish a websocket connection with the node-red instance running in Bluemix. This is a known issue when accessing from certain networks that is usually resolved by accessing the application using https rather than http.

I am building a web server using tide framework and I want to debug api function when server receive the request. However,when I click debug button on vs code, and using the curl command from terminal to send request to server, the terminal said "Failed to connect to port 3000,Connection refused". Does anyone know how to debug the rust web server on vscode?
I also had the same issue when I tried the code on this documentation page https://docs.rs/tide/latest/tide/. I'm going to assume that's what you're trying to debug?
I went to the github repository and there is a readme with a similar, but different example https://github.com/http-rs/tide. It works for me, and I could debug without any further issue using the rust-analyzer and CodeLLDB extensions.
Note: I had to restart my computer. After the first example failed I thought I'd try the curl command with a Node Express server to make sure there wasn't something blocking the request. After restarting this went away.
I'm attempting to do some development on iOS for a model-viewer web component through browserstack (using iOS 13 Chrome) and it seems unable to connect to localhost, whether I use bs-local (as suggested via browserstack), my IP, or anything else.
I went through their troubleshooting guides with no success, and their own "Debug Connectivity" test in localhost:45454 seems to return a 200 OK response for my page, but live.browserstack.com still seems unable to connect (it returns "Unable to display the page").
I'm attempting to run it using iOS 13 on Chrome.
I've set up the proxy details, enabled 'Force Local', and installed the Browserstack Local app and have verified that it is connected correctly. The URL formats I have tried are:
http://localhost:8000/dev/index.html
http://bs-local.com:8000/dev/index.html
http://bs-local:8000/dev/index.html
http://<my-ip>:8000/dev/index.html
I am writing my code in VS Code and am using node.js/npm and npm run serve using Ubuntu (WSL) in the terminal to start the web dev server, which starts on its own correctly. Opening the page on my own machine seems to work fine, it is solely unable to connect through browserstack live.
Is there a step that I'm missing? What should I troubleshoot next? I'm a junior developer, so please explain in detail.
I have 2 versions of my app deployed on the cloud. They both have same address, but different cloud instance names.
I am able to debug one application from cloud, but when I try to connect to the other one, eclipse gives the error:
Error launching a Cloud Debugging Session.
Server returned 409 (Conflict) for URL: 'address'
Another debugging/profiling session to this application seems to be active.
There is no sessions available in Debug view. I even restarted eclipse and my machine.
Is there a way to kill all/any debugging/profiling sessions in eclipse?
I was able before to switch debugging from one cloud app to the other but today I get this issue.
In FireFox I load my web application which has a Source Map. The Source Map seems to be loaded correctly, as the Debugger tab shows the original source files.
However, the Console tab contains only links to the compiled code, instead of the Source Map code.
Is a Source mapping done in FireFox Console?
Do I have to enable anything?
Update: I also tried it in chrome and there the console shows the original location of the event, BUT: only the first time after starting chrome AND only, if I first load the page and then open the developer tools. Exactly same behaviour in opera (same engine...)
Update 2:
As of Firefox bug 670002 Web console does still not support source mapping.
In chrome the source mapping works more than once if I directly embed the source mapping instead of using an URL.
For chrome developer tools, the answer was covered in this issue:
https://bugs.chromium.org/p/chromium/issues/detail?id=633549
In some cases, developer tools requested the source map file when no connection was alive anymore. It tried to open a new connection, which failed silently because of an invalid ssl certificate.
You may run into this, when:
You serve using https
You do not have a valid ssl certificate (which may happen often when you just run a quick local node.js https server)
Your https server closes the connection fast or immediately
Especially when your https server sends connection:close in the response headers you may run into this.
The biggest issue is, that this request is not shown in the network tap nor in the console, it is just silent.
Is it possible to view the network traffic (http requests, raw http etc.) similar to chrome dev tools (network tab) generated by an application (nodejs if it makes any difference) via vscode?
This functionality is already present, but it doesn't show the requests and responses of the application running.
The developer tools are connected to the running instance of Code and not the application you are executing. Currently it is not possible to view network traffic for the application you are launching from Code.
You can try to start from mbehr1.vsc-webshark plugin and use WireShark tools for catching your app network i/o.
It would be great a more detailed post about configuring launching Rust app (server) in debug mode, wireshark with VSCode integrated UI, and maybe internal browser in a single launch.json action, but I can't point anything close to it.
