I am trying to add extensions into blocked extensions list and got an error while saving the setting.

The error saying:
JavaScript error encountered in method
ZaXFormViewController.prototype._saveChangesCallba ck
name: TypeError message: 'cnt' is undefined number: -2146823279
description: 'cnt' is undefined.

Is there a way to do that using CLI?
