"Show Full Post" button doesn't work in subfolder installations

Did you edit the output before you shared it? Just looking at the embed_url value it’s

“``https://tecnoblog.net/noticias/paramount-oferece-us-108-bilhoes-em-dinheiro-para-tomar-warner-da-netflix”``

Could you just run the same command again, but this time:

./launcher enter app
rails c
TopicEmbed.find_by(topic_id: 157441).embed_url

If what you shared is indeed the value of embed_url in your db, then that is the issue, and I’ll make a small PR to discourse/discourse to handle edge cases like this where the embed_url has ended up in a malformed state.
