Hello,
Thank you for getting in touch with us.
That is just an issue on the backend. Your actual AMPs will not have any issues and you can test them here:
https://search.google.com/test/amp
and
https://search.google.com/structured-data/testing-tool/u/0/
You can safely ignore the error if your actual pages are not throwing any errors and everything is fine in your Google Search Console too.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
