Geometry union takes exceptionally long and crushes the script?

I am in 3D -> Electromagnetic Wave -> Eigenfrequency. My geometry involves union and difference operations as shown in the attached .mph file. The attached .mph file runs without error.
However, when I try to script it in MATLAB as in the attached .m file, the lines involving geometry union
model.geom('geom1').feature.create('uni1', 'Union');
model.geom('geom1').feature('uni1').selection('input').set({'cyl1' 'cyl10' 'cyl11' 'cyl12' 'cyl2' 'cyl3' 'cyl4' 'cyl5' 'cyl6' 'cyl7' ...
'cyl8' 'cyl9' 'sph1' 'sph2' 'sph3' 'sph4' 'sph5' 'sph6' 'sph7' 'sph8'});
model.geom('geom1').feature('uni1').set('intbnd', 'off');
model.geom('geom1').run('uni1');
take exceptionally long time to execute and eventually lead to the crush
Java exception occurred:
java.lang.NullPointerException

Why is it error-free when in COMSOL GUI, but leads to a crush in MATLAB scripting? How may I fix it?
Thank you so much in advance!
Best regards,
Alvin
