Hello,

I’ve moved your post to the section dedicated to reporting false-positives and false-negatives:

How to Report a False-positive / False-negative

Hey SonarSource Community! False-positives happen, as do false-negatives, and we’re eager to fix them. We are thrilled when our users report problems, so we can make our products better. What is a false-positive (FP)? A false-positive is when an issue is raised unexpectedly on code that should not trigger an issue, or where the suggested action doesn’t make any sense for the code. What is a false-negative (FN)? A false-negative is when an issue should be raised on a piece of code, but isn’t. …

Could you please share code snippets in text format? Screenshots are difficult to work with.

Thank you!

Hi @shanyi-front,

indeed, this is a bug. Seems the root scope of the script body is not properly handled in that rule. I created a ticket to fix it.

Thanks for reporting!
