I have followed the README, I have all environment variables set but "npm test" fails:
[11:30:32] I/launcher - Running 1 instances of WebDriver
[11:30:32] I/local - Starting selenium standalone server...
[11:30:32] E/launcher - Error: Error: Server terminated early with status 1

at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
[11:30:32] E/launcher - Error: ReferenceError: browser is not defined
How can I define the browser?
