No media uploads after update to 3.12.0-0-gd71d523 OTP

Good afternoon, I did the 3.12 OTP update this afternoon and the admin-fe update as well using the OTP update guide. Nothing stood out as an error and everything seemed to exit cleanly. I restarted the daemon and I was able to log in and I see posts send/receive well and functions like the remote Translate call work. My one quirk is I’m no longer able to change avatar pics nor upload jpgs to post with (but I have verified that the instance serves up pre-existing images attached to notices just fine).

Looking at the journal log: I get the following lines of interest:

I see where it’s actually depositing the files in the uploads folder (in my case /var/lib/akkoma/uploads/). I also don’t see anything odd in the Upload section in Admin-FE.

What might I have missed in the update/instructions? (the original install was the OTP from 2023.8 and I went straight to this one skipping the 2024.2 release) Any suggestions are appreciated, thank you.

I forgot to do the post-3.12 update instructions for media, didn’t I… (for some reason, since mine is a fully self-contained instance, I didn’t think I needed to, but I’m guessing that was a mistake)

edit: that was it. A Base URL is needed all the time, not just for remote media servers. My bad.
