Structured Data Errors

Hello! I’m getting intermittent Structured Data Errors that are preventing indexing of my pages.

You can see the errors here: https://search.google.com/structured-data/testing-tool?url=http%3A%2F%2Fwww.thefilmchair.com%2Fdivergent-tests-our-tolerance-for-dullness%2Famp%2F#url=http%3A%2F%2Fwww.thefilmchair.com%2Fdivergent-tests-our-tolerance-for-dullness%2Famp%2F

The logo error does not appear to be the problem, but the image error is. Is there something I should be doing with the images themselves to prevent this?
