Meta description length needs to be between 50 and 320 characters

You want to make sure that your meta description would fit the screen of any devices so keep it brief otherwise, customers won't see it and will defeat the purpose of generating click-throughs from search engines.
How to Fix:
Keep your meta description length between 50-320 characters
