As a result of a separate case involving the intersection of javascript embeds and [WP Discourse](https://github.com/discourse/wp-discourse) embeds we standardised this handling across both methods of embeds. See [Apply TopicEmbed url normalisation to embed urls inserted in the PostCreator by angusmcleod · Pull Request #30641 · discourse/discourse · GitHub](https://github.com/discourse/discourse/pull/30641)

So the entire issue here is because the above PR started removing trailing slashes from TopicEmbed in January this year? I feel conflicted about this change. I’d prefer we respect what the admin sends us to be honest.

I think this is the root of our issues.

Can you please run the following @Thiago_Mobilon

```ruby
url = "https://tecnoblog.net/noticias/governo-renova-app-da-cnh-para-baratear-obtencao-do-documento"

fd = FinalDestination.new(url, validate_uri: true, max_redirects: 5, follow_canonical: true)

uri = fd.resolve

puts uri

html = FinalDestination::HTTP.get(uri)

puts html.truncate(200)

```

The `fd.resolve` should be able to add the trailing slash on the `puts uri` line. I’m afraid it is failing.
