Cache custom endpoint woocommerce

Changed route to https://abs.imservtest.ru/wp-json/wc/v3/products
Plugin still doesn’t work.

function wprc_add_imserv_prod_posts_endpoint( $allowed_endpoints ) {
    if ( ! isset( $allowed_endpoints[ 'wc/v3' ] ) || ! in_array( 'products', $allowed_endpoints[ 'wc/v3' ] ) ) {
        $allowed_endpoints[ 'wc/v3' ][] = 'products';
    }
    return $allowed_endpoints;
}
add_filter( 'wp_rest_cache/allowed_endpoints', 'wprc_add_imserv_prod_posts_endpoint', 10, 1);

function wprc_add_cacheable_request_headers( $cacheable_headers ) {
    $cacheable_headers['wc/v3/products'] = 'authorization';
    return $cacheable_headers;
}
add_filter('wp_rest_cache/cacheable_request_headers', 'wprc_add_cacheable_request_headers', 10, 1);

mu file exists!

Found also this

1. Caching is working with default endpoints in wp/v2, works fine, quite fast, 50-100 ms.
2. Caching is not working with custom endpoint in wp/v2

Hi @johnferz

Thank you for using our plugin!

I know it has already been a month since your last post, so maybe you already solved the issue. But I do see the x-wp-cached-call: served-cache so your endpoint seems to be cached?
By the way I also noticed your endpoint isn’t returning valid json, but rather a single string of what seems to be escaped json.
