User-authored JavaScript found on page (Critical issue)

I’ve recently(starting 08/07/2017) started getting this error in my webmaster console and I currently have 71 errors and still counting.

The AMP test page https://search.google.com/test/amp?utm_source=wmx&utm_medium=link&utm_campaign=wmx-agg&id=gmSAYMdhsm2C2bI16K5cXw shows that is it NOT a valid AMP page and don’t know what’s causing this as I didn’t do any recent changes for any of my plugins besides regular updates.

Can someone tell what’s going on and what should I do in order to solve this issue?

I see that my amp pages are getting deindexed from google results so this is critical.
