I am using magento 2.2.4. The site is working fine. But everyday I got a sitemap error email. The below lines are in the email.
Sitemap Generation Warnings
Invalid header line detected
Also an exception is logged in to the exception.log.

Please help me to resolve this issue.

It is an issue with the litemage cache extension. I have upgraded the extension to latest version and the issue is resolved
