It looks like your post doesn’t have any tags that I can see by calling from API. The two current replies I see to your post have a tag of type “mention” for you because they are responses to you. After I post this, I’ll see what tags this one includes (as I am on kbin so it may work differently).
On kbin, I have found that posts to a magazine automatically include a tag of type “hashtag” of the name of that magazine, so it’s an interesting difference between the two applications.
Finally, on Mastodon, hashtags do create tags of type “hashtag” in a post, which is sensible and uninteresting.

This post to you has also included a tag of type “mention” but no extra tag of type “hashtag”. So, there you go.
