Many build errors when importing from blockbench

I have been trying to add my blockbench entity model for several days now, everytime its between two errors. I have tried both Mcp mappings and Mojmaps, I have switched from 1.18 to 1.16(my final should be in 1.16). Exported as java entity and have imported the model, the model shows up but after making the living entity it breaks.

I am making custom SMP with friends and just trying to add an ant. My friend said it way be a size limit to entities, I made the model at the size 4 by 3 by 3 blocks. If possible I do not want to remake the model smaller.

Thank you!
