Email Field not required still erroring
New to development so not sure what I'm doing wrong. Heres my problem. I have a post request for a bunch of data, all the fields are set to 'No' not required but when I Post data any other data type other than 'text' always reports back as invalid format. In my case, its email, int and bool, must be in a valid format. I'm not passing data to it so I thought 'No' on required field would be good enough to be just blank but I guess not... what am I doing wrong and why is it ignoring the 'NO' not required?
