Node.js: Chai Expect issue with Try/Catch

I have several form fields that I'm testing with Chai Expect. I'm using a Try/Catch with return statements, but after all the wrong inputs (in the form) I get only one error, that is the first one, but I need to catch and log all the errors and I don't know what I'm doing wrong...Any help would be aprecciated. The code:

//CHAI EXPEXT
        var inputs = [response.fname, response.surname, response.age, response.password, response.email, response.phone, response.city, response.country, response.postal_code];

        for (var i = 0; i < inputs.length; i++) {

            try{

            expect(inputs[0]).to.be.NaN;             
            expect(inputs[7]).to.have.length.above(1);         
            expect(inputs[3]).to.have.length.above(6);
            expect(inputs[4]).to.match(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/);
            expect(inputs[4]).to.have.length.below(256);
            expect(inputs[2]).not.to.be.NaN;

            return "OK";

            }catch(error){
                console.log(error);
                return error;
            }


        }
