XMLHttpRequest Exception 101 while launching chrome dev tools - google-chrome-devtools

I was trying to make modifications to the chrome developer tools and so I followed the steps listed here : https://developers.google.com/chrome-developer-tools/docs/contributing
and installed chrome build 155617 from continuous builds archive. And then I launch the chrome as follows :
chrome.exe --debug-devtools-frontend=C:\path\to\155617\devtools_frontend --remote-debugging-port=9222
When I try to inspect an element, I get the dev tools panel, however, none of the "Elements", "Resources" etc., panels are functional.
So to debug this, I inspect the devtools and I see the following errors in the console :
Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101 utilities.js:855
Uncaught TypeError: undefined is not a function Panel.js:314
Any idea how to fix this ?
Thanks for your help.

I've filed a bug https://bugs.webkit.org/show_bug.cgi?id=96211
Not all the required files were zipped into devtools_frontend.zip probably because we had switched to lazy loading schema. I'll try to fix it tomorrow.
The simplest way to fix that is to copy the content of WebKit/Source/WebCore/inspector/front-end from the repository into your unzipped version of devtools frontend.
You can get the current front-end from the repository with help of svn checkout https://svn.webkit.org/repository/webkit/trunk/Source/WebCore/inspector/front-end command

Error when clicking on a link that opens a pop up on moodle 3.5

I have updated my module from moodle 3.2 to moodle 3.5 and receive these errors in the debug web console:
moodle-core-event: Global event published: FORM_ERROR
yui_combo.php?rollup/3.17.2/yui-moodlesimple.js:5828 moodle-core-event:
Global event published: BLOCK_CONTENT_UPDATED
These errors show when opening a pop up with atto editor so notes can be saved. Unfortunately, I can't save the notes and it seems the above errors are causing the issue.
I have tracked down a similar error on the moodle forum site:
https://moodle.org/mod/forum/discuss.php?d=367647
However, no solution has been marked. Sadly no apache errors are showing so I can't narrow down the problem.
Can someone shed some light on these errors?
Just checking the obvious, but did you purge the caches? Javascript is cached
Administration > Site administration > Development > Purge all caches
or
php admin/cli/purge_caches.php
I always turn the cache off in config.php in a development environment $CFG->cachejs = false; but never on production, which has caught me out before.
Also, you might need to run grunt to minify the javascript files, then add the minified files to the git repository
https://docs.moodle.org/dev/Grunt
If your javascript is in a folder called amd
grunt amd
If your javascript is in a folder called yui/src/something
grunt shifter
Or just
grunt js

Flutter error: Unable to locate gradlew script

I can't run all of my flutter apps, because in the console appears everytime this error message:
Downloading Gradle Wrapper... 1,2s
Launching lib\main.dart on SM G960F in debug mode...
Running Gradle task 'assembleDebug'...
Finished with error: Unable to locate gradlew script. Please check that C:\Users\...\android\gradlew.bat exists or that C:\Users\...\android can be read.
I try to fix this problem more than ten hours and don't find a solution.
I will advise you to check your pc properly for unwanted programs. Something is preventing your pc from running the Gradle. I had the same issue only to realize that antivirus was installed on my pc alongside a cd burner that I just installed. Check for any antivirus that might be preventing Gradle from running.
I also faced the same error initially. While creating a flutter application from scratch I just ran the default flutter application which is a counter app in a flutter. I faced the same issue at first. If you are in this same context as described earlier the following could be the solution
1.Java 8 is more suitable for the flutter/android development. The next versions of java have some exceptions. I used the Java 14 and stuck at this issue for some time
The next could be the JAVA_HOME path in your environment variables. If it is not provided the set the JAVA_HOME path.
Run flutter --doctor and check the requirements if satisfied like Android SDK is updated or not, upgrade flutter if required. In some cases having good Internet connection also plays a role in this issue some times.
These are the major points to be satisfied in order to get rid of this error. Mostly this could be the a solution or part of it.
The error suggests that something is preventing gradle to run properly on your machine. Check whether you have any unwanted programs or anti-virus on your machine running that might be preventing gradle to run. If so, remove or stop those programs / anti-virus and try again.
After that, delete the .gradle folder located here C:\Users\yourPcName\.gradle containing the unfinished file and try again . It will work now .
You can also manually download Gradle and map it in Android studio , Learn more with this article here .
Warning, the gradle versions change quickly, so make sure you manually
downloaded the exact version that flutter wanted to download and the
download failed. Download the gradle here and then replace it in the
gradle folder.
C:\Users\yourPcName\.gradle\wrapper\dists\gradle-x.x.x-all
If it still doesn't work,
Try to run flutter --doctor
From a console window that has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:
C:\src\flutter> : flutter doctor
This command checks your environment and displays a report of the status of your Flutter installation. Check the output carefully for other software you might need to install or further tasks to perform (shown in bold text).
You can learn more here :
If flutter doctor itself doesn't work, then know that flutter is not installed on your machine (or you forgot to add it to the environment
variable).
I also faced this problem and I made something to run my app on android
tried to open anything on android files and android studio ask me if I want to open for editing android file in android studio then click on it and it will open android project then click run enter image description here

Why does running a .NET Core application from VS Code cause an error to occur?

I am trying to run a .NET Core version 1.1 application from inside VS Code version 1.8.1. When I push the F5 button, the console appears at the bottom of the screen. After enabling tracing, I get this output:
Reading fx resolver directory=[C:\Program Files\dotnet\host\fxr]

Also, a bar appears at the top of the screen that says:
The preLaunchTask 'build' terminated with exit code 2147516564.
When I click the "show problems" option, a blank problems tab appears that contains the message:
No problems have been detected in the workspace so far.
Why is VS Code refusing the build the project, and why are there no problem messages? I am only posting this on SO, because Google was not helpful, and because the VS Code GitHub page recommends asking questions here first.
UPDATE
This problem was caused by me having put coreclr.dll in C:\Program Files\dotnet. I did this, because of a different problem related to building the app. I thought that, since the output mentions it is looking in this directory, it might be helpful to put this file here. It turns out that this was a very bad idea, as it just complicated the problem! LOL!
You can get this error if you have problems in:
packages - please check if all packages are ok and restored successfully
core version - check that core installed with correct version
.net tools - please check if version of .net tools correct.
Can you try visual studio?

Strange GWT behaviour in IE8

I experience a problem with GWT 1.6 in IE8 (I have enabled native XMLHTTP support).
The scenario i this: The first time I enter a page, it renders fine with no problems. But in subsequent requests, the page fails with a JavaScript error:
Message: Exception thrown and not caught
Line: 5067
Char: 237
Code: 0
URI: http://someurl/somehashcode.cache.html
It happens in both standard mode and compatibility mode. The strange thing is that I do not experience the error when I run the application on localhost through the ASP.NET dev server. Only when I run it from a Windows 2003 server.
Does anyone have an idea, why this happens?
I would appreciate any kind of help - thanks in advance.

You always use the last version of stable release of GWT. This kind of error is from GWT compiler and you must report it to GWT team. Maybe this problem fixed in the last version of GWT.
I've seen the same issue, my feeling its coming from cached files. When the response is not from cached files I didn't see an exception.
I'm doing SSL to IE8. Microsoft have a fix you could try:
Internet Explorer file downloads over SSL do not work with the cache control headers
http://support.microsoft.com/kb/323308
Internet Explorer 7 and Internet Explorer 8
To resolve this issue in Internet Explorer 7 and in Internet Explorer 8, follow these steps:
1. Start Registry Editor.
2. For a per-user setting, locate the following registry key:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
For a per-computer setting, locate the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
3. On the Edit menu, click Add Value.
4. To override the directive for HTTPS connections, add the following registry value:
"BypassSSLNoCacheCheck"=Dword:00000001
To override the directive for HTTP connections, add the following registry value:
"BypassHTTPNoCacheCheck"=Dword:00000001
5. Quit Registry Editor.
