I get this error when trying to validate my Twitter Summary Card. I’ve tried both Summary and Summary with large image. get this error:

Unable to render Card preview
Log:
INFO: Page fetched successfully
INFO: 19 metatags were found
INFO: twitter:card = summary tag found
ERROR: Invalid value (message: Field description failed to validate because: text expects tag property, but not found in Map().)
WARN: Not whitelisted

You have no twitter:description field. According to the Summary Card documentation, this is a mandatory field.

I’m using Yoast SEO that supposedly does it automatically.

I was able to fix this. I had to:
Go into the Home page itself and add both the meta description and a featured image. It now works great!
