Unpermitted parameters | configure_permitted_parameters

+1 https://github.com/lynndylanhurley/devise_token_auth/issues/897

devise (4.3.0)
devise_token_auth (0.1.42)

class ApplicationController < ActionController::API
  include DeviseTokenAuth::Concerns::SetUserByToken
  before_action :configure_permitted_parameters, if: :devise_controller?
  respond_to :json

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
  end
end

It's still not working here.
Any solution?

The issue names no repository file or test; begin by reproducing the provided ApplicationController configuration with devise 4.3.0 and devise_token_auth 0.1.42. Trace the signup parameter-sanitization path and existing authentication tests, then verify that the submitted name is accepted during signup without permitting unrelated parameters.
