Hello @easazade
Thank you for creating this issue. We will investigate it and get back to you as soon as we have some feedback.

Hello @easazade ,
Thank you for creating this issue and providing detailed information about the error you encountered.
Based on the error you've shared, it appears that the problem occurs when the self-hosted runner trying to create a directory at /Users/runner/ but doesn't have the adequate permissions to do so.
To overcome this, you need to ensure that the directory exists and the runner has the right permissions to access and modify it. In advanced-usage.md, you can find a comprehensive guide that can assist you in setting up the necessary permissions.
Completing the steps detailed in the document ensures the self-hosted runner has the necessary permissions to create directories and write to them, which should fix the permission denied error you're encountering.
Hope this helps!

Looks like this could be fixed by #708 👀

Looking at the logs the user on self-hosted runner is /Users/appledev/ while the action attempts to access /Users/runner for some reason.
The advanced-usage.md linked above doesn't take into account cases when it's not allowed to modify users/user groups or touch files outside of runner home directory

Hello👋, I'm going to close the issue for now because this is current behaviour of the action as described in comment .
In case of any issues please feel free to reach us out.
Thankyou!

In case of any issues please feel free to reach us out.

@priya-kinthali Can you prioritise merging #708 which will fix the current, invalid behavior?

If you don't have sudo permissions you can't modify other user's files (using a self-hosted runner you don't fully own), so while the current behavior works as documented it doesn't seem to work as intended :/
