"Referenced AMP URL is not an AMP" error in Google Search Console

Good morning. I recently received the following error today from Google Search Console: "Referenced AMP URL is not an AMP"

It affected eight pages in our site:

May I ask for your assistance in fixing this?
Thank you.

We are getting the same errors for all of our client's blogs that are on hubspot as well.

We got this error on four HS blog posts as of 7/9/19. In Google Console, I clicked the links that it showed as impacted, which rolled out a menu on the right from which I retested the live versions. All came back as valid AMP pages, so it seems like either HS or more likely Google suffered some short-term difficulty in parsing for AMP. Either way, the problem seems to have corrected itself, at least for us.
