[bug] Launching Devtools on palette fails if useNewWebBrowser is set to True

[JeromeBriot]

Hello,

I finally found what was going wrong with my add-ins. 😒

See this message: Debug of palettes stopped working

Setting useNewWebBrowser to True in palettes.add() makes the Devtools unusable when right click on a palette object.

Tested on Windows and macOS.

I followed the workaround suggested by @saketsatta here, but these lines appear in the command window whenFusion 360 starts:

[18656:17168:0410/155939.519:ERROR:tcp_socket_win.cc(341)] bind() returned an error: Une seule utilisation de chaque adresse de socket (protocole/adresse rÚseau/port) est habituellement autorisÚe. (0x2740)
[18656:17168:0410/155939.520:ERROR:devtools_http_handler.cc(220)] Cannot start http server for devtools. Stop devtools.

Hi Jerome,

I will look into it and let you know what I find.

Thanks,

Hi Jerome,

I was able to reproduce the problem.

The good news is that we have identified a fix for root problem and it should be available early next week with a Fusion update. So you will be able to debug the HTML/JS without the need to launch Fusion from the command line.

Thanks,

@saketsatta , I just tested with the latest update of Fusion 360 (2.0.8111) but it didn't work on my computers (Wndows and Mac). 

Both "Dev Tools" entries open the "Inspectable pages".

"Save page" and "View page source" don't work neither.

Hi Jerome,

I'm sorry to hear that. Does any of the inspectable pages you see have the page with your html? If you click on that, does it show you the source code? If not, can you please post the images of what you see when you click on both the Dev Tools options?

Thanks,

Here are some message related to DevTools that appeared in the terminal:

It works if I click on "Dev Tools (In-product / Chromium v69)" and then on the HTML file in the inspectable pages list.

The HTML file is also listed when I use "Dev Tools (Punch-out / Chromium LATEST)" but it opens a blank page when I click on it.

Hi Jerome,

I'm glad to know it works if you use the In-Product version of DevTools!

Which version of Chrome do you have currently? If it is v80 then as per this post the punch out version of DevTools will also work if you downgrade to v79: https://stackoverflow.com/questions/60292131/qt-qwebengine-remote-debugging-chrome-developer-tools-n...

I have Chrome v81. So I will use the In-Product version of DevTools. It works great on both Windows and macOS.

Thank you..

Thank you for confirming this Jerome. I will follow-up on the original thread so everyone is clear about it.
