template include - Why isn't template_include working with AMP correctly?

Before you ask I have looked around the similar questions to find a resolution but I couldn't find one that worked.

• Ive tried the permalink option several times,
• There is nothing in my htaccess file that would be causing the 404
• There's no caching software installed
• There are no other plugins that im using for redirection or amp
• The is_single() works perfectly fine but the is_page() does not, i've also tried is_front_page(), is_category(), is_home(), is_page('specific page') but again dont seem to work.
• body_class() is included in the body tag.

So I'm really not sure why it isnt working, see code.

define( 'AMP_QUERY_VAR', apply_filters( 'amp_query_var', 'amp' ) );
add_rewrite_endpoint( AMP_QUERY_VAR, EP_PERMALINK );
add_filter( 'template_include', 'amp_page_template', 99 );
function amp_page_template( $template ) {

if( get_query_var( AMP_QUERY_VAR, false ) !== false ) {


    if ( is_single() ) {

        $template = get_template_directory() .  '/amp-single.php';

    } 

    if( is_page() ) {

        $template = get_template_directory() .  '/amp-page.php';

    }

}

return $template;
}

Any answers would be greatly appreciated, cheers :)

• 1 What’s the problem exactly? You mention 404, templates have nothing to do with 404 errors. – Milo Commented Oct 19, 2018 at 12:50
• Im getting a 404, it's supposed to got to the amp-page.php page template. Like the single posts do when you goto the page then put /amp/ – M0n5terBunny Commented Oct 19, 2018 at 16:33

Your endpoint is only applied to posts, add EP_PAGES to generate rules for page post type-

add_rewrite_endpoint( 'amp', EP_PERMALINK | EP_PAGES );

That should also be within a function hooked to init.
