error “File Input” is required value Magento 2

Question

I have a customer attribute that is "File Input", type is file and require is true but I do not let it show in customer register. When I try to create an account it displays the error like this:

How can I ignore this error without changing the require of the attribute?

Answer 1

• If the attribute is required but not provided at customer creation it fail backend validation. Consider a default value.
• To remove frontend validation you have to make sure the attribute is not used in said forms.
• Each Customer Attribute has a value that controls in which forms is used.
• That value is called used_in_forms and it can be altered in an install script with the help of the Magento\Customer\Setup\CustomerSetup entity.

E.g. This piece of script makes the Customer Attribute is_authorised be used only in adminhtml_customer form.

             /**
             * is_authorised
             */
            $authorisedAttribute = $this->customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'is_authorised')
                ->addData(
                    [
                        'attribute_set_id'   => $attributeSetId,
                        'attribute_group_id' => $attributeGroupId,
                        'used_in_forms'      => ['adminhtml_customer'],
                    ]
                );
            $authorisedAttribute->save();
