The gitgraph extension shows this error:

Error loading webview: Error: Could not register service workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..

[mhutchie]

I'm the author of Git Graph, which is one of the extensions that is affected by this (as my extension leverages Visual Studio Code Webview's for it's core user interface). This Service Worker error occurs within Visual Studio Code's Webview implementation, so it affects all extensions that use Webviews. It prevents the Webview from loading, for all the affected users.

mhutchie/vscode-git-graph#508 includes an image of a stack trace of this error in the first comment.

This bug first appeared in Visual Studio Code 1.56.0, and only occurred for numerous Linux users (but definitely not all). Reports of this issue lasted about a week or so, so I assumed it had been fixed in one of the 1.56.x patches. However, with the release of Visual Studio Code 1.57.0, I've now had reports that this issue is occurring again.

Looping in @mjbvz - Are you able to provide some assistance?

[tritemio]

For information: restarting the PC solved the issue for me ATM.

So, it may be related to some sort of cache that is cleared after reboot?

This issue appeared for me twice, every time after a vs code update. The first time updating from 1.55 to 1.56 and now updating from 1.56 to 1.57. I don't know if the fix on 1.56 happened after a reboot as well.

[sketchbuch]

I also have this issue on Linux, be good to get a fix soon.

Update: Rebooting fixed the issue, thanks @tritemio

[joyceerhl]

I'm on Windows and can repro this error in a new blank Jupyter notebook.

Duplicate of #122951

[grandrew]

Rebooting is not an option for me, and I love the Git Graph extension. As well as ability to view images and other neats within vscode tabs. Please consider re-opening and fixing. Thanks

[eduncan911]

@mjbvz please reopen this issue. @deepak1556 just stated in #122951 that Linux users are a separate issue, even though it still has the Linux tag.

[eduncan911]

Copying my comment from the "Windows" thread...

Running vscode 1.58.1 on Linux.

Multiple extensions that use WebView all error with:

Error loading webview: Error: Could not register service workers: InvalidStateError: 
Failed to register a ServiceWorker: The document is in an invalid state..

code --no-sandbox does not help, same errors.

However, changing my --user-data-dir (that forced a re-install of all extensions) did make it work!

Obviously, that is not preferred due to many years of customizing - that I do not want to start all over with.

I tried to downgrade to VSCode 1.55; but, when opening a file now for webview, it doesn't seem to trigger the extensions any longer (something broke).

[deepak1556]

Please provide the trace following the steps below:

• Open vscode like code --enable-tracing="navigation,net,loading,rail,ServiceWorker,disabled-by-default-loading" --trace-startup-file="/tmp/chrometrace.log"
• Perform the steps that leads to the the service worker error
• Quit the application
• Attach the chrometrace.log file generated at /tmp

OS: Linux x64 5.11.0-18-generic snap

We can see that all the reported issues happen with the snap version of VS Code. It is an unofficial build. It would be a fix to install the official build of VS Code.

I think that's incorrect.

Right at the top of the Installation page, it says it's the official distribution method for VSCode:

Snap#
Visual Studio Code is officially distributed as a Snap package in the Snap Store

https://code.visualstudio.com/docs/setup/linux

Snap is highly preferred over Deb packages because it is sandboxed, isolated from corrupting the system.

[tamuratak]

I think that's incorrect.

Thank you for your correction.

[enkeyz]

For me it occurs anytime I install an extension, which opens up their setting page right after. Restarting vscode fixes the issue for some time.

[tp1050]

rm -rf .config/Code/Service\ Worker/{CacheStorage,ScriptCache} followed by pkill code worked for me without restarting my whole machine.

worked like a charm.

[wafflemakr]

I just hit this issue with the latest release trying to display the Release Notes. I deleted ~/.config/Code/Service Worker (+ all directories with Cache in the name) and now it's working again.

This worked like a charm for me in Ubuntu, remember to refresh VSCode! thanks a lot!

[Tyriar]

This isn't a linux/snap issue, I've seen it plenty of times on Windows.

[QuentinSc]

Get it on windows, on a fresh install

[saadazghour]

If you are using Ubuntu, there is probably another (maybe hidden) vscode process, which is causing the problem.

Close the vs code first and in terminal try: killall code

[mminot-yseop]

Got that all of a sudden on 1.87.0. OK after reboot but I hope it won’t come back too often. 😆
(Xubuntu 20, .deb package install)

[fabriceleal]

This could be a blink bug, maybe resulting from some sort of race condition ... the error is triggered here https://github.com/chromium/chromium/blob/main/third_party/blink/renderer/modules/service_worker/service_worker_container.cc#L427-L430

The provider_ might not be set at creation

[juanma-avio]

Easy workaround on Linux:

1. exit vs code
2. in the console write: "killall code"
3. start vs code again

[caiqichang]

i got this problem when i open second vscode windows.
only first vscode window can work well, webview in the other windows broken down.

vscode version: 1.89.0
pc: windows 11

[yan-pi]

Same issue Here!!

Does this issue occur when all extensions are disabled?: No, sice i need to install the markdown extension to occur

VS Code Version: 1.89.1 dc96b83 x64
OS Version: linux fedora 40 linux kernel 6.8.9-300.fc40.x86_64
Steps to Reproduce:

Install markdown preview or other Rxtension that uses webview
Run the command to show webview

[BMourguesFieldbox]

rm -rf .config/Code/Service\ Worker/{CacheStorage,ScriptCache} followed by pkill code worked for me without restarting my whole machine.

worked like a charm.

Same, worked perfectly, quote replying for future readers

[Doc-Tiebeau]

rm -rf .config/Code/Service\ Worker/{CacheStorage,ScriptCache} followed by pkill code worked for me without restarting my whole machine.

Works for same issue when displaying markdown and png files.
