"You can't perform that action at this time" when I star a repository

Bug

Body

Whenever I star a repository, I get this message at the very bottom of the page:

The interesting part is that the feature actually works without issue(you can see the repository is successfully starred when you refresh the page), but just when you click the star button, that message shows up and the star button doesn't get updated(like it doesn't change from 'Star' -> 'Starred').

It's been about a week or two and it still is not resolved...

@Helloyunho I'm still running into the same issue in mid-October.

Try clearing the web browser's cache and logging in again to the account. I was facing the same. Got resolved by this.

[Helloyunho]

I tried this just now but I'm still having the same issue

[mjfos2r]

I am also having the same issue and unfortunately that did not resolve it.

[MrDevel0per]

Thank you! Unfortunately, this didn't solve the issue for me.

I also having the same issue

@Helloyunho @mjfos2r @MrDevel0per I also have this problem and have figured out why it happens. It's because Github uses the Element.checkVisibility API (at https://github.githubassets.com/assets/behaviors-934d11c22368.js), this API was added after Chrome 105.0, so any chrome version less than 105.0 will cause an error. Github has actually abandoned lower versions of Chrome.

Solution

To implement a polyfill for the Element.checkVisibility method. I provide a ready-made tampermonkey script to achieve this. Fix "You can't perform that action at this time" for Github

Update: It seems that github just fix this issue last week which may need a few weeks to deploy to production. github/browser-support#47

[Helloyunho]

This works! Hope GitHub deploys this soon to the public

[xiaohk]

Looking forward to the fix!

This still does not work on Safari. Can you please remove "Marked as answer"?

[Helloyunho]

I'm using Safari and it works
tho I'm using AdGuard to inject the script

[landsman]

I still seeing this issue in my latest Safari. What should I do?

[MrDevel0per]

I downloaded Safari Technology Preview, which supports the API.

[landsman]

That's crazy. I operate on the latest browser and GitHub does not give a fuck.

[mjfos2r]

I also am still having this bug

[frankjonen]

Still doesn't work here. Just updated Safari as well.

Hey @Helloyunho !

1. Check Authentication:
   Ensure that you are authenticated and logged into your GitHub account. If you are not logged in or there are authentication issues, GitHub may restrict certain actions.

2. Verify Permissions:
   Make sure that your GitHub account has the necessary permissions to star repositories. If your account has been restricted or if there are issues with permissions, it might result in the error.

3. Review GitHub Status:
   GitHub may experience service outages or disruptions. Check the GitHub Status Page to see if there are any ongoing issues. If GitHub is experiencing problems, you may need to wait until the issues are resolved.

4. Clear Browser Cache and Cookies:
   Clear your browser's cache and cookies. Cached data may sometimes interfere with the proper functioning of GitHub features. After clearing the cache, try starring the repository again.

5. Use a Different Browser or Device:
   Try using a different web browser or device. Sometimes, browser extensions or configurations can cause issues. Using a different browser or device can help identify if the problem is browser-specific.

6. Check for Browser Extensions:
   Some browser extensions, especially those related to privacy or security, might interfere with website functionality. Try disabling browser extensions one by one to identify if any of them are causing the problem.

7. GitHub Support:
   If the issue persists, and you have ruled out common solutions, it may be worthwhile to reach out to GitHub Support for assistance. Provide them with details about the issue and any error messages you encounter.

As you can see in the answer, the problem is that GitHub uses the new Element.checkVisibility function that Safari doesn't seem to support yet. Using the polyfill in the answer fixes this problem.
PS: Did you even read the thread properly lol
PPS: When does GitHub update their polyfill? It's been a few months since this polyfill is merged...

[Usman-52]

i'm facing the same issue as you had (You can't perform that action at this time) Did you soloved the issue or still remain?

[ChristianVaughn]

Seems it still doesn't work on safari. surprised they are using a feature this new that all major browsers do not support yet.

[Helloyunho]

it's actually more like Safari not regularly applying their JS update from technical preview to official release

[xiaohk]

I agree with @ChristianVaughn. It feels GitHub has jumped the gun by using checkVisibility on production without a polyfill.
