Hey Everyone, I have following this article/tutorial [Create BDD test cases in Katalon Studio | Katalon Docs](https://docs.katalon.com/katalon-studio/bdd-testing/create-bdd-test-cases-in-katalon-studio) to create automation test using BDD. When I run it, this error happen: `java.lang.UnsupportedClassVersionError: META-INF/versions/21/com/fasterxml/jackson/core/io/doubleparser/FastDoubleSwar has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0` Please everyone help me! ---

@albert.vu @Elly_Tran Problem in Katalon Studio using BDD again and again! Katalon documentation MUST publish a page in order to explain a complete/definitive resolution for the bug arround BDD/Cucumber. Where is it? I find it nowhere in [https://docs.katalon.com/](https://docs.katalon.com/). It’s a shame. Are you going to ask users to continue helping each other? ---

I have created a boilerplate project for this common issue, here is the repository link: [GitHub - depapp/sample-bdd-project-in-katalon-latest-version: This project is a boilerplate setup for Behavior-Driven Development (BDD) testing in Katalon Studio, compatible with both versions 9 and 10. It provides a structured template designed to streamline the development and execution of BDD tests using Gherkin syntax.](https://github.com/depapp/sample-bdd-project-in-katalon-latest-version) anything feedback/suggestion is really appreciated ---

@depapp Thanks you for your great project. @albert.vu Katalon publishes a sample BDD (Cucumber) project > **[Sample BDD (Cucumber) project in Katalon Studio | Katalon Docs](https://docs.katalon.com/katalon-studio/get-started/sample-projects/behavior-driven-development/sample-bdd-cucumber-project-in-katalon-studio)** > > This sample demonstrates fundamental behavior-driven development (BDD) testing. The application under test (AUT) is the react calculator//katalon-studio-samples.github.io/calculator. To learn more about BDD testing, you can refer to this document:... This one does not work since some version around v9.5. How about updating it while learning from @depapp’s contribution? ---

Hi, Thank you for your information. I have let my team know and will review the issues with Katalon Doc about BDD/Cucumber. Thank you!
