Hi! Here's my json file (I changed it to a Word doc so I could upload it) and a screenshot, at the bottom of the Word doc, of what's showing up when I trade with the wandering trader. I used one item from each of the mods I have installed that I know aren't working, but its not the single item I have in the json file. For example, all of the items for Artifacts give the same result as the one I have in here. Hope this helps!

Hi! Sorry I haven't gotten back on this issue lately. I've been using the 1.17 version of Better Wandering Trader, and I'm experiencing the same issue. The difference this time is that the only custom trades I can make are with vanilla Minecraft items, and no items from mods work. I've attached the new json5 file, as well as the mods I currently have installed, in case there's a specific mod that could be causing the problem. I don't know much about mods and making them, so I'm not sure if another mod could cause the problem, or how I could find that out.

Thank you for your patience, the artifact and bunch of trinkets mod trades seem to be working on my end.

I'm going to run a few more tests with the other mods, but I would wager that one mod is causing all the other trades to turn into air.

The items from all the mods in your doc can be added as custom trades to the wandering trader, except for nomad books. However, this is only because you had the wrong namespace for nomad books in your document. It should be "nomadbooks" not "nomad_books". Trying making that correction and let me know if the problem still persists.

Sorry for the late reply! I just checked again, and unfortunately I'm getting the same results. What's odd is that some of the mods that aren't working have worked in the past. I don't know what the cause of that would be, but my guess is that it could be that I've gotten a new computer since the mods that I've used before worked, or maybe because I've added new mods to my game since having a new computer could be causing a bug with them. Like I've had Artifacts, Nomad Books, and Ward Blocks all work before, so my best guess would be that something else I've added is giving some sort of problem with those for some reason.

Are you using the latest version of Fabric API? I know from experience that some mods built on earlier versions of the API may cause compatibility issues.

I'm not, but in testing to see if that would work, the game crashes when trying to start, probably because something else I have isn't updated to the newest API. Guess I'll have to figure out what is causing that now lol

Once you figure it out, please let me know and I'll test it on my end.
