can someone tell me best way to bug fix this?
I've got this in Chrome Console
Uncaught TypeError: Cannot read property 'setCustomerId' of undefined
at HTMLButtonElement.onclick ((index):560)
In admin/sales_order_create/index/ - when I select Create New Customer nothing is happening???
Solved! Go to Solution.
Since this functionality works well by default, we can suspect on 3rd party modules and your custom code. In order to debug it, try to turn off 3rd party Magento modules (only one at the same time) until you find what causes that.
