No errors with express-validator isEmpty

Question

I am using express-validator 5.2.0 in a expressjs app. I implemented the validaiton on a form data. But it does not capture the errors and gives empty errors object. When validation runs it shows the "no error" when I submit the empty form. It should follow the error path and should display the error.

Answer 1

check('firstName', 'First Name is required').isEmpty() is enforcing firstName to be empty.
You will want to change that last part to .not().isEmpty(), so that you invert the isEmpty validator.
