Answer 1

From what I understand you are getting the error because of your rules set to that model. In your model rules, this field for the file is set to be required for all scenarios.
One possible solution is to set the field to be required only on insert scenario and leave update scenario to be not required for the field. But this really depends on business logic that you need to satisfy.
