I tried to reinstall the server multiple times but nothing worked and I keep getting the same error... I do have the correct java 21 installed or whatever it was. I couldn't find whats causing this problem as I tried a lot to reinstall the files again and again. -

OK, what I need is to be able to take a JSON string, from a config file or data pack, and convert into NBT that can be applied to any arbitrary item (technically, item stack). This could easily be done in 1.12.2 using JsonToNBT.getTagFromJson(String data) like so: NBTFromJsonWrapper(String label, String data) { super(label, label); try { wrapped = JsonToNBT.getTagFromJson(data); } catch (NBTException e) { System.err.println("Exception reading json-nbt string: " + e.getMessage()); wrapped = new NBTTagCompound(); } } However, I can't seem to find a way to do this in newer version, specifically 1.19.4 (though once I'm done updating to that version I plan to be updating the latest 1.20 and 1.21 version). This was previously used for several purposes, one was simply to create purely vanilla potions. The other was to create special items, primarily as trophies albeit practically useful trophies, often in the form of Easter Eggs. (I also had a homebrew system along side it, but I don't think I'll be updating it.) Any help would be appreciated. Surely there is still a way to do this, and codecs do not seem to be the answer. -

The security check is a captcha which shows below the question. If it doesn’t show for you, make sure your ad blocker is disabled as it may be hiding it. -

I had the same issue, and it took me quite some time to figure out the solution. It turned out that when I downloaded the mod through CurseForge, the system automatically added a unique identifier to the file name, and Forge could not recognize it due to this naming issue. Unfortunately, it wasn’t immediately obvious, and I wasted quite a bit of time troubleshooting. At the time, I was under a tight deadline because I was participating in a competition where we had to implement specific game mechanics. If you are experiencing a similar issue, I recommend checking the mod's file name in your mod folder. Ensure that it matches the exact version Forge is looking for.
