Nextcloud version: Nextcloud Hub 8/29.0.1
Operating system and version: Debian 12.5
nginx version: 1.22.1-9
PHP version: 8.2.18
The issue you are facing:
This instance originated back in the owncloud days and was converted/upgraded step by step to nc29 (along with in-place operating system upgrades - I still have ancient PHP 7.0 config files around - though nothing that old is installed anymore 
)
Users have been relying on plain text and markdown editor app which long has been deprecated and do not work with NC29 at the moment, but neither does the text-app right now.
I’ve enabled/disabled the app both via occ and within the WebUI, played with the various configurations but so far, if a user tries to open a .md file, it will be downloaded instead of opening it in the WebUI.
Is this the first time you’ve seen this error? Yes, immediately after the upgrade
Steps to replicate it: Unsure due to long history

Also omitted for the time being, which one is more relevant, local one of of the reverse proxy?
Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.
Initially libresign seems to handle this file but errors out (to me, the URL looks somewhat wrong):
{
"reqId": "[redacted]",

"remoteAddr": "[redacted]",

}
after disabling this workflow wants to handle this, but the URL looks weird again (/ missing?)

Anyone with an idea what the core problem is?
