help with "keyframe handler"

I am making an animated block using geckolib in collaboration with blockbench. In blockbench, my animation uses particles which display correctly inside of blockbench, but when I import the animations and model to MCreator, there are no particles. The animation functions in all other ways, but there are no particles, and I receive the error code saying

Particle Keyframe found for FTileEntity -> procedurecontroller, but no keyframe handler registered

F is the name of the block in this case (for testing purposes) and I activated the animation through procedures when placed. What does this mean and how can I fix it?
