Chaining check causes duplicated errors

request.check('email', 'Email is not valid').notEmpty().notNull().isEmail();

With no “email” field set this will return 3 repeatitions of the same message. Shouldn’t the error message be unified on chained call like this?

Thank you

Hi everyone! The fix for this has finally landed in v3.0.0!

req.getValidationResult().then( result => {
  var errors = result.useFirstErrorOnly().array(); // enjoy an array with no duplicated errors for any given parameter!
})

Hi @TheHominid. I’m glad that you found something that works for you at the moment.

Anyway, with the introduction of #269, it’s easy to add opt-in support to new methods that fix issues like this. That’s my plan, so this issue can finally be closed.
