Not 100% sure if this is a Summit issue or something in Lemmy more generally. Here’s the post in question:
https://midwest.social/post/10123989
The link to the blog works on my instance for the desktop. Several other users were reporting the link being broken, and it does break for me on Summit, as well.
When I hit the link on Summit, the requests on the server are GET /api/v3/post?id=2024
and GET /api/v3/comment/list?max_depth=6&post_id=2024&sort=Top&type_=All
. It looks like it parsed out the “2024” from the original link and tried to use that in a Lemmy API call.
I found the cause. It will be fixed in the next update.
