This is right.

Applied the suggestion: Roel Bollens (@RoelBollens-TomTom) and Seth Fitzsimmons (@sethfitz) can you re-up your approval?

Hi amir-rezaei — thanks for this contribution! There's just one thing blocking the merge: the DCO check is failing.

What's wrong

DCO requires every commit from an external contributor to carry a Signed-off-by: line. Your commit is missing it:

How to fix it

I think the simplest way to fix it is:

1. Hard reset your branch to the current version of main.
2. Re-apply your change (it's pretty trivial) so it should be easy.
3. In the same commit if you don't mind, apply the change that Copilot requested to de-indent line 51.
4. Commit with --signoff
5. Your branch should now just have one clean commit that's complete and carries sign-off. Force push that.

At that point the DCO checks should pass and it should be merge ready.

Again thanks!

Approved, but there are other indented lines that remain which deserve the same treatment (as well as making it lint-clean). I'll send a follow-up.
