Why is the AMP tool saying I have invalid structured data when the structured data tool shows no errors?

Why is the AMP tool saying there's missing or invalid structured data on http://www.tasteofhome.com/recipes/flavorful-chicken-fajitas/amp when the structured data tool shows no errors?

In addition, I'm not able to see a preview of the rich card in the AMP tool like I can for other recipes like https://allrecipes.com/recipe/19621/eggs-on-the-grill/amp/.

If you check https://allrecipes.com/recipe/19621/eggs-on-the-grill/amp in the AMP tool, we get this message:

"Page has valid structured data. This page is eligible for extended AMP features."

Google has instructions on how to get rich cards for recipes (https://developers.google.com/search/docs/data-types/recipes), but i'm not sure if we're violating anything other than image aspect ratio.

Thanks!
