Grape + Cucumber | number of arguments

hello, in my tests with cucumber I have a problem.

I'm getting a wrong number of arguments (given 1, expected 0) (ArgumentError) error when I try to make a request.

I make a request that is missing parameters, I should get a 400 error with the missing parameter message.

    params do
      requires :field_a, type: Integer
      requires :field_b, type: Integer
      requires :field_c, type: Float
      requires :field_d, type: Float
      optional :active, type: Boolean
    end
    post do
      result = WorkitProductCategory.create_or_update(params)
      present result, with: Api::V1::Entities::Pmp::WorkitProductCategoryObject
    end

so is my rescue_from:

  rescue_from Grape::Exceptions::ValidationErrors do |e|
      Rails.logger.debug(e)
      error!({ error: e.message, class: e.class.name, errors: e.errors }, e.status)
    end

Start with the shown Grape params block, post endpoint, and rescue_from handler, then reproduce the Cucumber request that omits required parameters. Done means the request returns HTTP 400 with the missing-parameter message instead of raising the wrong-number-of-arguments error.
