I am not sure if this has been answered as I am not really sure of the problem. At least once (sometimes more) during the day I get a notice that Ubuntu crashed. The info says it's related to the chrome-gnome-shell(I have reinstalled chrome-gnome-shell). I also can't get my local Gnome extensions to list at: https://extensions.gnome.org/local/. Using the browser console in Firefox, I get the following when I bring up that page:
Unchecked lastError value: Error: Could not establish connection. Receiving end does not exist. ExtensionCommon.jsm:265
stderr output from native app org.gnome.chrome_gnome_shell:

I am running Ubuntu 14.04 Gnome (v3.8.4), Linux kernel 4.4.0-71, Firefox 52.0.2 32-bit.
Any ideas of what is wrong and how to fix it?
You are using old chrome-gnome-shell version.
Just upgrade.

I have a Flutter Web project, and when an error is thrown, I can't open the dart file where the error was thrown, because the error line points to a JS file:

How can I make it to show the dart file where the error occurred, instead of a JS file?
I'm using Flutter Channel stable 2.5.2, Android Studio version 2020.3.
I have found a workaround for this issue.
You basically have to install a third-party patch; it will translate the paths in JS and point to the right line in dart file.
Download the patch and follow the instructions here: https://github.com/obeobe/flutter-web-exception-mapper
Optionally you can see trace of dart files in the browser.
Make sure you have source maps enabled in your browser.
got the answer from this link on github
Python 3.6.4 (32 bit x86) using slackclient locally connects to the RTM API and is able to listen in on slack channel changes. That same code running in Azure (64 bit AMD) does not work.
I've made sure that the Azure python install is as close to my local machine as possible. There are a few package discrepancies (see below) though this should not be the issue since these are not being used:
Azure vs. Local Machine
* numpy 1.15.3 vs. numpy 1.16.0
* pyodbc 4.0.24 vs. pyodbc 4.0.25
* pytz 2018.7 vs. pytz 2018.9
* setuptools 38.5.2 vs. setuptools 28.8.0
I've looked at the following links though I am not sure they will help. Some of the instructions for setting up a proxy in Azure are no longer valid (off by several steps). Recently Azure stopped serving a web app of mine (C#/ASP) when I changed the (totally unrelated Python) setting below.
Application settings->General settings->Python version (from Off to 3.4)
It was a real pain to get it back. I think that I will need a proxy though I would imagine Azure should provide better instructions for this. I am somewhat of an Azure newb though not new enough to start changing things willy nilly!
make Python 3.x Slack (slackclient) use a corporate proxy
Custom Slack Bot cannot connect
https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/application-proxy-configure-connectors-with-proxy-servers
https://learn.microsoft.com/en-us/azure/azure-functions/functions-proxies
import time, logging, os
from slackclient import SlackClient
from datetime import datetime
def main():
#proxies = dict(https="proxy.azure.com:443", http="proxy.azure.com:443")
sc = SlackClient(BOT_TOKEN)
CHANNEL_ID = "some channel id"
logger.debug("Listening to channel '{0}' with id '{1}' for the following actions: ".format(CHANNEL_NAME, CHANNEL_ID))
if sc.rtm_connect():
logger.debug("Connected to Slack!")
while True:
# Read latest messages
# If activity is in CHANNEL_ID do something
else:
logger.debug("Couldn't connect to slack")
On my local machine I get the following (I cut out some of the code):
DEBUG - Listening to channel 'news' with id 'CFDQ3BXYZ' for the following actions:
DEBUG - message_replied
DEBUG - message_deleted
DEBUG - message_changed
DEBUG - Connected to Slack!
However, in Azure, I get the following:

DEBUG - message_replied
DEBUG - message_deleted
DEBUG - message_changed
DEBUG - Couldn't connect to Slack!

It appears that WebJobs are restricted to port 80 only. So there is no way to open up ports, etc. on Azure WebJobs at least at this time (see article/post below). So it appears that a VM or some other route is the way to proceed.
Can I open ports on Azure Websites?
NWJS Version: v.0.32.1 (Tested on different 0.31 versions also and 0.32.beta)
Operating System: Linux only. Tested on Ubuntu 16.04 LTS x64 and Elementary OS 0.4.1 Loki x64
Expected behaviour
The program must respond.
Actual behaviour
The program not responding and if I break it (Ctrl + C) i seen in console that messages:

But if I'am using nwjs-builder-phoenix and running SDK - working correctly.
How to reproduce
Prepare
Download and extract fake data to parsing: https://github.com/trofivan/myq-jobs-archive-parser/releases/download/v0.1.0/fake-data-big.zip
git clone https://github.com/trofivan/myq-jobs-archive-parser.git
cd myq-jobs-archive-parser
npm i
Working correctly (only with nwjs-builder-phoenix SDK)
npm start
In the opened window click Select folder to parse
Select folder with fake data
Wait some time while data will have parsed.
Use filters
Close the program
Working not correctly
npm run build.dist
cd dist/myq-jobs-archive-parser-0.1.3-linux-x64/
./myq-jobs-archive-parser
Select folder to parse and waiting some time.
The program does not respond.
Close program (Ctrl + C or [x] on the window) and see console output:
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

PS:
If download nwjs from the official website, working not correctly with SDK version also.
On Linux system program not responded when comes to the game Web Worker: https://github.com/trofivan/myq-jobs-archive-parser/blob/master/src/middlewares/fetchJobs.js
When program not responding I'm can not open Chrome dev tools and get more info.
I have a Crossbar.io server with PHP Thruway workers. Recently, I started getting the following error. It happens about once a day now:
2016-04-17T21:08:12+0000 [Router 9572] Unable to format event {'log_logger': <Logger 'crossbar.router.protocol.WampWebSocketServerProtocol'>, 'log_time': 1460927292.17918, 'log_source': None, 'log_format': 'Traceback (most recent call last):\n File "/usr/local/lib/python2.7/site-packages/autobahn/wamp/websocket.py", line 88, in onMessage\n for msg in self._serializer.unserialize(payload, isBinary):\n File "/usr/local/lib/python2.7/site-packages/autobahn/wamp/serializer.py", line 106, in unserialize\n raise ProtocolError("invalid serialization of WAMP message ({0})".format(e))\nProtocolError: invalid serialization of WAMP message (Expected object or value)\n'}: tuple index out of range

2016-04-17T21:08:19+0000 [Controller 9565] Guest worker2 exited with error A process has ended with a probable error condition: process ended with exit code 255.
Does anyone know hot to prevent this?
How do I automatically restart the worker if it fails as in this case?
I solved it in linux with MONIT checking crossbar-controler process and adding the following line:
if children < 3 then restart
3 is the number os child processes that crossbar-controler has on my environment. If any of them exits then crossbar restarts itself and notifies me. You have to check the number of child processes you have running using:
sudo service crossbar status.
This solves the error exit worker but with a cost of restarting the crossbar-controler. I am convinced that must be a crossbar/thruway way of solving the problem.
The ideal way is to try catch all possible errors of php to prevent fatal worker exits.
Thanks
Bit of info: Python 3.2.3,
Cherrypy version 3.2.2. Windows 7 64-bit.
Installed Cherrypy, set up PATH with the right Python directory, etc. However, whenever I run the tutorial file (tut01, Hello world) or any other python file with the same code, I get the following output:

Pretty sure I did everything correctly according to the installation guide on the Cherrypy website. Not entirely sure how to fix it, but I'm guessing it has something to do with the import errors. Has anyone else had success with installing cherrypy on windows for python3?
Found a solution: https://bitbucket.org/cherrypy/cherrypy/issue/1110/cherrypy-322win32exe-installer-didnt
The original installer was missing the wsgiserver3 module, which was needed for it to work on Python 3.x. The above installer should fix the issue.
I struggled with this, there is a simple solution:
clone the repository to your local machine.
navigate to the root folder and execute the following command: python setup.py install
It is mentioned in the README.txt here in the official source repo.
Just to notice that this is a answered question, quoting rashdanml:
