You are using add/subract/multiply operators on a 3-dimensional list of values (3D vectors). You should use the required functions to perform these operations on 3D vectors.

Example:

Code:

delta_vector = subs3(tool_pose_global.Pos(), object_pose.Pos())
direction = mult3(delta_vector, 1.0/distance)
