...
        HTTP_AUTHENTICATION_CREDENTIALS = ''
        private_constant :HTTP_AUTHENTICATION_CREDENTIALS

        DEFAULT_OPTIONS = {
            scale: 1,
            displayHeaderFooter: false,
            headerTemplate: '',
            footerTemplate: '',
            printBackground: true,
            landscape: false,
            pageRanges: '',
            format: 'A4',
            width: '',
            height: '',
            margin: { top: 36, right: 36, bottom: 20, left: 36 },
            preferCSSPageSiz: false
        }
        private_constant :DEFAULT_OPTIONS
...
... (around line 73)
                    httpAuthenticationCredentials: options.has_key?(:http_authentication_credentials) ? options[:http_authentication_credentials] : HTTP_AUTHENTICATION_CREDENTIALS
                },
                pdfOptions: DEFAULT_OPTIONS.map { |option, value| [option, options.has_key?(option) ? options[option] : value] }.to_h
            }.to_json
        end
...
