Looking up this error online, this might be a driver issue. Could you try updating your graphics driver and try again?
Edit: Nevermind. See MC-128302
Maybe the issue is the structure itself? Did it work in 1.12.2? Are the spawn conditions for monsters being met?
Confirmed - I'm pretty sure this has been the way it is for ages though.
