Hi! I've noticed that there is an error in CI, and I've already investigated it. It looks like the error may be caused by something else. I'll create an issue for it later.

As for this PR, it's just a small change, and you can easily verify it manually.

If you have any other idea, just tell me!

Thank you for your contribution. The CI error was caused by other reasons (inappropriate testing script), and I will merge this PR. Thank you again.
