Hello @wordmeto
Thank you for contacting us, Can you please send your site health information along with the PHP error log using this form privately. So we can further investigate the issue.
It would be helpful if you could open up the Network panel in DevTools to see what the response is for that request so we can determine why it is not valid JSON. It could be some caching plugin, for example, that is corrupting the JSON format.

Also, the AMP plugin works well with PHP 5.6, There was an issue reported in version 2.2.2, which was fixed in 2.2.3, I will recommend updating AMP plugin to the latest version ie 2.2.4.
JFI We are planning to bump the minimum requirement for PHP to version 7 (Github Issue), so I will recommend upgrading to PHP 7.4, ASAP

As we didn’t receive a response I’ll mark this as resolved. Feel free to open a new support topic if you require any further assistance.
