Many thanks for reporting. The API URL changed from a sub path to a sub domain 😄. Fixed with: 8fd0327

I wonder whether it is worth a live patch. As of the small change, it would be an easy one 🤔. So people do not need to next DietPi release.

[MichaIng]

Okay, while the live patch works, there is a dedicated issue, which cannot be patched that easily: Minecraft 1.20.5 and above requires Java 21, available on Debian Trixie only. So we need to install v1.20.4 in that case. So the live patch does not make sense: We fix the download, but the service won't start successfully on Bullseye and Bookworm systems. I fixed it for upcoming DietPi release: e0430a7

[MichaIng]

Hmm, pinning older Minecraft version is now awesome either. But installing new Java versions on older Debian is as well not that trivial, and can conflict with other software titles. Though we have a request for this very reason: #4505

... wait, it has become much easier now to install other Java versions: #4505 (comment)

Just commenting here to just express how crazy such a tiny change is so disruptive to many different projects .. it took me embarrassingly long to find out why my personal server wasn't working.

I had just updated my own script that updates my own server and set it to run the next day... The next day happened to be when they changed the API ... Took me a day or two to realize why my server wasn't working and that it was only downloading 0kb paper jar files 🤦

[MichaIng]

Yeah, for APIs this is especially nasty 😄. Would have been trivial to add a redirect, and inform people through other channels about the deprecated old URL. Though I cannot rule out this has happened, and we just missed it. There is no real way to add deprecation messages to the API itself, without distorting the output either.

If you actually stored the empty response, then I suggest to update your script. E.g. in case of curl, use the -f flag to print the HTTP error to STDERR, and use -o to store the actual response body, if there is any and no error, instead of shell redirect >. This way you see such errors in the output and store content only on successfull 2xx responses.
