Minecart issue | Error running job content is null

[samve000]

Describe the Bug

When I place down a minecart the log shows an error and the minecart becomes a black square. When I remove the Create mod the minecart is normal again, when I remove the better fletching table mod it becomes a minecart with a command block in it and the error won't show up.

Reproduction Steps

1. Install create mod
2. Install Better Fletching Table mod
3. Open a world
4. Place a minecart

Expected Result

I expect the minecart not to be a black square and the error not to pop up everytime I place a minecart.

looks like BFT's datapack hacks are breaking flywheel somehow. Needs to be tested with flywheel 1.0 once that's ready
