What happened?

Hi, I got this error when running test in CircleCi. It works well in local.

2024-06-11T10:00:50.349Z ERROR @wdio/config:ConfigParser: Failed loading configuration file: file:///home/circleci/project/wdio.conf.ts: Unknown file extension ".ts" for /home/circleci/project/wdio.conf.ts
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /home/circleci/project/wdio.conf.ts

I use the WebdriverIO Starter Toolkit to init project WebdriverIO + mocha + typescript.

Do you have any suggestion?

What is your expected behavior?

It works well in local and CircleCi

How to reproduce the bug.

Init project by: WebdriverIO Starter Toolkit
npm init wdio@latest .

It works well local but failed in CircleCi

Relevant log output

Hey @nghhung , thanks for raising the issue. Unfortunately I don't see how anyone could investigate this issue as there is no information about your Circle CI environment. There are many resources as to why [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" appears and I would recommend to start with that. In WebdriverIO v9 we are moving to tsx which should eliminate this problem.

At this point I can only close this issue as it is impossible for us to assist you here. Let me know if you have any specific questions.
