Interesting, looks like a bug on hive.blog! I forwarded the issue to the Hive developers. I started working on an update for hive.blog that will support truvvl embeds, I just checked and the error in your post is also gone in that update.
For now, you can view your post on Peakd Beta: https://beta.peakd.com/hive-100037/@progressivechef/travel-nature-mauritius-photography-travelfeed-20210422t230226519z
Excited to see more truvvl stories from you!
