Custom errors with passwordless login using lock

I am trying to display a custom error signifying that the wrong one time code was entered using passwordless login with lock. The error returned is:

{"error":"access_denied","error_description":"Wrong email or verification code."}

The dictionary file for lock v11 doesn’t specify “access_denied” as an option. Also, the documentation says to use the following for an invalid email:

    passwordless: {
        'bad.email': 'The email is invalid'
}

However, this doesn’t work because the error that is returned for an invalid email is instead ‘bad.connection’, and so I’ve had to use following:

    passwordless: {
        'bad.connection': 'The email is invalid',
},

Any help would be appreciated, thank you.
