The following required properties are missing: og:type, og:image, fb:app_id.
og:image should be of 1200 pixels x 627 pixels. Currently it is a logo. I recommend using screenshot https://www.coding-guidelines.lftechnology.com/docs/introduction/ as og:image
Also add twitter:cards meta tags.
Use https://developers.facebook.com/tools/debug/ to test.
