Issue with running a script calling "parts" function on the MATLAB Online R2019b

The function causing the problem starts as below:

function submitWithConfiguration(conf)
  addpath('./lib/jsonlab');

  parts = parts(conf);
the error I get is :  
  'parts' requires one of the following:
  Navigation Toolbox
  Robotics System Toolbox
  Sensor Fusion and Tracking Toolbox

Error in submitWithConfiguration (line 4)
  parts = parts(conf);
