FOC Simulink (MATLAB 2020a) Errors

When I run the simulation the inverse Park transform gives me one dimensional vector errors. I don't understand why this is happening.

Hi everyone,

I am trying to develop an FOC algorithm (see screenshots attached) using the Motor Control Blockset in Simulink but I am getting the following errors (see screenshot attached). I don't know waht I am doing wrong since I fed my d and q currents to my Discrete PI controllers and fed the results straight into my Inverse Park Transform. I don't know how to solve this and any help would be greatly appreciated.
