Hi all,

Welcome to the community and thanks for these reports!

I’ve combined them because they seem remarkably similar to me. Could you share the conditions under which you get this error?

Thx,
Ann

algophren · October 11, 2023, 7:56pm

Hi Ann, thanks for responding.

In my case, I’ve noticed that the issue arises only when I delete a line while refactoring the code. Also, it feels a little bit like the SonarLint is interfering with GitHub Copilot… But I’m not sure enough.

Nicolas_Roquebert · October 12, 2023, 8:54am

Hi all,
I have no idea in which context this occurred.
Maybe just after a SonarLint plug-in update (along with Copilot?) in PhpStorm.
I am also using GitHub Copilot that was in version 1.3.0.
Let you know if I can reproduce it.
Nicolas

Thank you both for the information,

@algophren you mentioned that the issue arises only when you delete a line while refactoring.
Do you have a simple code example that this occurs?

Nicolas_Roquebert · October 12, 2023, 1:52pm

I just reproduced it without doing something special.
I was looking to the MR report in sonaqube, and then suppressing a function parameter in the function definition and in its call in the same PHP file, in PHPStorm.
And the error appears in the seconds.

Hi, to give an update, we identified the issue, and the fix will be part of the next 10.0 release happening later this month, on the 31st of October.

Thank you for your reports!
