Magento2 copied value using Jquery, but getting error like this is a required field

I have added a custom field for example - artist price, the value of which is being copied to price field but when saving the form, I am still getting error this is a required field The code I am using is like: $("[name='product[artist_price]']").change(function() { $("[name='product[price]']").val($(this).val()); }); what I understand is that since the value is being copied and not filled using the keyboard, it assumes that the field is still empty or something else I am not sure. also after testing I want to hide the field product[price], so how I can achieve this without getting the validation error. he complete html code for the target field is like this: <input class="admin__control-text" data-bind=" event: {change: userChanges}, value: value, hasFocus: focused, valueUpdate: valueUpdate, attr: { name: inputName, placeholder: placeholder, 'aria-describedby': noticeId, id: uid, disabled: disabled }" name="product[price]" aria-describedby="notice-G2FT2Q2" id="G2FT2Q2" type="text">
