I was in similar situation and couldn't find relevant resolutions:

Quick Answer: After upgrade to VS Code 1.56.2, make sure to remove old breakpoints and create new breakpoint and at-least have 1 breakpoint and launch.json available.

Lengthy details:

I have similar issue for python scripts when I start the "debugger bar" I see it for a couple of seconds the top debugging bar and then it disappears. Bu then no message on the console, nothing. I tried reinstalling VS Code, enabling/disabling extension, various restart.

• OS and Version: Mac OSX Version 11.4 (20F71)
• VS Code Version: 1.56.2
• Extension: Python v2021.5.842923320 by Microsoft

RootCause:

What I did know for sure that I updated my VS Code, and after that this mysterious issue start happening, so when to release log of VS Code 1.56.2. I found below release log

Debug view displayed on break#

The default value of the debug.openDebug setting is now openOnDebugBreak so that on every breakpoint hit, VS Code will open the Debug view. The Debug view is also displayed on first session start.

So VS code Version 1.56 release, debugger will only show when at-least 1 breakpoint is found. However, looks like there is issue with their internal code checking for historical breakpoint data after VS Code upgrade..

CORS (cross origin resource sharing) is a widely used security mechanism to only allow client-side browser applications on the same domain to access resources or APIs. Anything outside the trusted CORS policy gets rejected. In the case of local web pages, files are considered to be outside your origin. Your browser essentially considers your hard drive to be on a different domain. Otherwise, malicious scripts would be able to easily access your local files by simply guessing paths to access.

As far as local CSS is concerned it is not considered as outside origin domain. You will get same error if you try loading css from some other domain.

To fix loading of local files you need some kind of web server or toned down dev server where your page can be hosted. One example of dev servers that can host static files: If you have Python installed python -m SimpleHTTPServer will start a server on http://localhost:8000/ in whatever folder you start it in

So apparently my issue didn't have anything to do with my IIS configuration. I still can't explain why it worked on http-server, but now I got it working on IIS, too.

After a lot of research and unsuccessful experiments, I tried to observe, what exactly ngsw-worker.js does that leads to this error. After putting some breakpoints and finding new keywords to search for I stumbled across this GitHub issue which led me to this much discussed issue. In one of his comments the user jackkoppa mentioned his StackOverflow Question where he found a workaround to fix such an issue.

Basically, I just added his script to our project and added the command for it to our project.json.

Here are the steps he describes:

To use the workaround: (Angular 5, tested w/ Angular 5.2.1)

1. npm install replace-in-file --save-dev
2. Include this script in your app, e.g. at build/fix-sw.js
3. In your package.json:

If you only need a single instance for the whole PWA, the best solution is a static class.

Another way you could do this is to use Edge Dev Tools to see the order of requests performed on the site.

When I open dev tools, and go to the network tab on that address, then search for 'No Products Found', I see that main.js does an XHR request to a URL, and then alternately displays that message:

[![using Edge DevTools Network tab to search for the string "no products found"][1]][1]

If this gives a response, it will render a grid of items, if not, it displays No products found.

Here's the URL it checks: https://pwathemes.com/demo-api/wp-json/pwacommercepro/products/?page=1&featured=1&order=asc&orderby=title&per_page=20

So an easier loop becomes this, checking that URL directly for products. If there are any, then No products found will not be displayed

According to https://caniuse.com/push-api it is only available via Apple’s custom protocol: Safari Push Notifications. This however requires an Apple App Id. Another solution would be to fall back on email/text message, or integrate with a notification app like https://pushover.net/

I'll try to break it up as much as possible, but there are plenty of things to be done.

• As per the documentation, when working with Flutter Web and Firebase, you need to add your Firebase dependencies in your index.html, like this:

Use the dependencies that you want, but if you aren't using analytics, leave it out. You have to import this first thing though firebasejs/8.3.0/firebase-app.js

This problem isn't specific to VSC debug mode. It happens whenever you try to sign in to Google in a Chrome instance that has debugging turned on. In other words, if you, your automation software, or IDE starts up chrome with a command like chrome.exe --remote-debugging-port=9222.

In both attach and launch mode the vsc attaches a remote port to control the browser.

A same issue raised at chromium issues :- https://bugs.chromium.org/p/chromium/issues/detail?id=1173641

To check in your google account security settings you can choose to allow less secure applications to access your account for debugging purpose.

The problem is the capture attribute.

According to MDN:

capture was previously a Boolean attribute which, if present, requested that the device's media capture device(s) such as camera or microphone be used instead of requesting a file input.

Also, the value of the accept attribute seems to be wrong (according to MDN). If it doesn't work try accept="image/*" instead.
