When we create a custom json recipe it works fine in single player but when you try to use it on a server the clients can never connect and instead get an error message.

We can even get the client connected and then add a json recipe to the server and /reload and it will immediately disconnect the client with the same error message.

We've verified they are valid and working recipes on the client as well. This happens with any size recipe we've tried. Seems to be an implementation problem with the codec.

As a follow up, we've done some more testing and this seems to specifically occur when using "-" key in recipes, we instead replace them with

          "O": {
                "type": "compactcrafting:block",
                "block": "minecraft:air"
            }

to enforce a check for air instead the recipes work and load fine on the server.

Further info: "-" actually seems to work everywhere except the corners, when used in the corners it causes the issues, replacing the corner blocks with air is working.. such a weird thing..
