Update error "has additional properties" to have array with additional properties names

[ceoworks]

Suppose we have a schema with such a properties userSchema = {name, surname}
But in he input we receive object that looks like input = {name, surname, login}
When validate accross userSchema, error must contain 'forbiddenProperties' array besides message and property fields.
Example: { message: 'has additional properties', property: 'data', additonalProperties: [ 'login' ] }

Kind Regards

I think that this would be awesome!

this is already possible. You only need to define schema properly.
For your example @ceoworks login should be defined as optional property.

Something like this:

 var schema = {
        type: 'object',
        properties: {
          name: {type: 'string' },
          surname: {type: 'string' },
          login: {type: 'string' }
        },
        required: [ "name", "surname" ],
        optional: [ "login" ],
        additionalProperties: false
      };

I believe this can be closed given @dmeznaric solution

I don't think that this is resolved, the original issue was about giving the property that was extra in the error output. I don't think that this is solved yet...
