New installation having trouble with derivatives.

Hi. I am setting up a site on WSL on an windows machine. Everything seemed to go well, but when I created my first repository item and tried to create associated media, I get errors. Specifically, I see this: milliner-1 | [2025-09-30T20:31:26.762820+00:00] app.ERROR: Caught exception saving media resource. {"Exception":"[object] (RuntimeException(code: 500): Cannot parse 'alternate' link header from response to HEAD https://islandora.dev/media/10/edit?_format=json at /var/www/crayfish/Milliner/src/Service/MillinerService.php:632)"} []
After some testing I can confir that the alternate link header is not being sent out. I have tried messing with the Islandora module, which sends out the link header, but haven't cracked it. Has anyone else had a similar issue? Thanks!

Sorry - I see my error - I did not properly configure Islandora.
