I hope this message finds you well. I wanted to bring to your attention that the golang lint CI did not pass on your recent PR. Upon further review, it appears that your code does not meet our code standards, specifically the lack of a space before the return statement.

Would it be possible for you to make the necessary adjustments to your code? This would greatly help us maintain our code quality and ensure a smooth integration process.

Thank you for your understanding and cooperation.
