Hi,

I have written the code mentioned in READme in both syntax ES6 and non ES6 but it is throwing below error:

TypeError: Class constructor Formatter cannot be invoked without 'new'

@neerjain I need some additional information:
Please provide:

• full source code for your Reporter file
• full stack trace
• Node version and flags you are running this under; also versions of transpilers (like babel) if you use any

[neerjain]

Please find below teh details:

1. Source code of Reporter.js file

`const CucumberJSAllureFormatter = require("cucumberjs-allure2-reporter").CucumberJSAllureFormatter;
const AllureRuntime = require("cucumberjs-allure2-reporter").AllureRuntime;

class Reporter extends CucumberJSAllureFormatter {
constructor(options) {
super(
options,
new AllureRuntime({ resultsDir: "./out/allure-results" }),

Node version: 8.11.3

I am running this through protractor conf.js file

cucumberOpts: {
strict: true,
format: ['node_modules/cucumber-pretty', 'json:./reports/json/cucumber_report.json', './util/AllureReporter.js'],
require: ["../testSpecifications/.js", "../util/.js"],

},

@neerjain After some experiments, it looks like there were some incompatible changes in Cucumber version 5.
Latest supported version is "cucumber": "^4.2.1" for now.
I've tested that your example works well after downgrade.
I will try to work on the support for cucumber 5, but can not promise any timeline.

[sseliverstov]

@neerjain possibly you need to fix tsconfig.json, here working example https://github.com/sseliverstov/allurejs-examples/tree/master/cucumber-js5-allure2. Also we copy @korobochka 's code to our organization https://github.com/allure-framework/allure-js.

[fescobar]

@korobochka can you release a new version of cucumberjs-allure2-reporter with the fix?
Thank you so much

[korobochka]

@fescobar : I am not maintaining this project anymore (everything moved to main Allure repo, but that version is not released yet).
If you can test tsconfig changes and submit PR here -- I'll release the hotfix.

[fescobar]

@korobochka I'll try to create the PR. What main Allure repo? can you share the link?
@sseliverstov can you give access to the example? or upload it here, please?
