On AMIMOTO Managed Hosting, we have set up New Relic client to hosting support smoothly when server failure. It inserts some scripts into your web pages to monitor the server performance. The script causes some errors on AMP pages.
To solve this issue, we AMIMOTO team has released the plugin Disabled NewRelic For AMP. It will disable New Relic client on AMP pages. Simply install and activate it to solve New Relic errors on AMP pages.
