The issues seems to be related to setting entity attributes in 1.16.

athrane · Answer 2 · 2021-08-17T15:54:40.000Z

The error happens when a new attribute is set, as opposed to modification of a vanilla attribute defined in net.minecraft.entity.ai.attributes.Attributes.

The new bassebombe attribute failing:
setAttribute(entity, DECOY, 1.0D);
