TypeError: Core.Telemetry is undefined

[RuneHanssens]

I followed the guide over at https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/test-studio-classic-pipeline-editor and I get the following error while running my pipeline:

Test method Microsoft.PowerApps.TestAutomation.Tests.TestAutomation.RunTestAutomation threw exception: OpenQA.Selenium.WebDriverException: TypeError: Core.Telemetry is undefined

Any idea what I'm doing wrong?
