Some of my twitter cards are not showing up.
For some posts, e.g. the below
they are showing fine.
But for most, e.g. the below,
I get the following error when I try to validate using the card validator:
ERROR: Invalid value (message: Field description failed to validate because: text expects tag property, but not found in Map().)
I’m using the yoast seo plugin.
Any ideas what could be causing this error or what I could do to fix it?
