I developed the auto-fill form, based on ng-select data it automatically fills the data. But the only issue I am facing is when I am trying to delete the selected data it's throwing me a Cannot read property 'pincode' of null error. Please find and try to resolve this bug. I am sharing my code below. Thanks in advance.
