After updating to php8.1 we're seeing these errors for metatags that have malformed token values. It is actually good to see that you have wrong tokens but still it is not nice to see errors popping up.

Use malformed token ([node:field_teaser_media:entity:field_image:height] - image style is missing) and reload the page.
I wonder whether metatag should handle this error more gracefully and notify site administrator somewhere else (perhaps hook requirements).
