Hi @tusharchavan,
Thanks for contacting us; I have checked your website, and the AMP validation is OK, but I saw a few errors related to structure data that information is defined by you SEO plugin, in this case, Rank Math. To register this information, you can go to the settings page of your SEO plugin and define all the required information in the metadata section.
If you need further assistance with that, please get in contact with the Rank Math support team.
But if you have any issues with your AMP pages, I saw that you are using a tagDiv theme; they have a custom solution built on top of the AMP plugin; I would suggest checking their documentation.
I hope that it will help
