WordPress API error when trying to add tags that already exist to a post

I’ve run into an error in the browser console whenever I try to add tags that already exist on the site to a post. I’ve managed to reproduce this on a completely new site.

To reproduce this, please try the following steps:
1) Create a few tags (around 5-6) under Posts > Tags.
2) Create a new post.
3) With the browser console open, start adding your tags to the post.
4) You should see a 400 Bad Request error for /wp-json/wp/v2/tags?_locale=user

I was able to reproduce this error on a completely new WordPress 6.0.1 install.
