After I update Magento version from 2.3.0 to 2.3.2 on checkout page I got knockout errors on my console and payments, product items do not show on-page. Before update, it works well.

    Uncaught ReferenceError: Unable to process binding "visible: function(){return isVisible() }"
Message: isVisible is not defined

  • Are you using vanilla magento checkout? Or one step checkout extension? – Dominic Xigen Jul 19 at 20:16
  • @DominicXigen onestep – Ashen One Jul 21 at 1:39
  • Hi if it is a commercial extension bought by 3rd party vendor then support can usually solve such issues. Your issue indicates that maybe your static assets are still from old version of Magento , clear all caches out (manually if needed) and try again. – Anton S Jul 22 at 7:50
  • Hi, did you finally solve this issue I have the same issue using the default Magento checkout ? – magentodev Sep 12 at 14:44
  • @magentodev hello, partially fixed. I replaced knockout parts from 2.3.0 and insert 2.3.2. It's partially fixed this issue, and I don't have an error, but still, troubles in front-end elements rendering (because of the custom template). So, replacing knockout js files may help you. – Ashen One Sep 13 at 8:55
