SEO.js og.url is blank

[donaldboulton]

Each page needs its own title, description, and url = not the site title, description, and url

Google Search on og.url

And in reality all page home page to posts or even a contact page needs it own meta information specific to the page. I have argued with the Gatsby community about this and it falls on deaf ears.

Go to my publiuslogic.com site and see meta data perfection on all pages or posts.

The above is done with react helmet in each page or posts templates and each query using canonical url's.

Tried many different ways with a single SEO component and never could figure out correct seo for all pages and posts

Line 88 of SEO.js

{ property: 'og:url', content: url},

I can get site url but not full path with

{ property: 'og:url', content: fullURL(path) }, I just get the site url

or trying

{ property: 'og:url', content: fullURL(pathname) }, = gives be no og.url???

Or add pathPrefix: /,
to site meta and then

const realPrefix = site.pathPrefix === '/' ? '' : site.pathPrefix
const url = site.siteUrl + realPrefix + slug

but slug is undefined.

A fix would be nice.
Thanks
