testcafe: Script that worked in version 1.5.0 but no longer works in 1.9.4.

@frejfrej, We can’t share a time frame as any personal estimations may be misleading. However, considering the activity in this thread, we’ve raised the priority for this issue. We will consider fixing it in one of our next sprints.

@Sabou44, Thank you for the confirmation email. I’ve reproduced this issue. I got a slightly different error message than the one you shared, but it’s clear that both of them refer to the same object. We need more time to investigate the issue. Once it’s fixed, we’ll update this thread.

For the team:

The error message:

1) A JavaScript error occurred on "https://wc-111-giessen.sodius.cloud/Windchill/app/#ptc1/tcomp/infoPage?ContainerOid=OR%3Awt.pdmlink.PDMLinkProduct%3A127278&oid=VR%3Awt.part.WTPart%3A127515&u8=1".
      Repeat test actions in the browser and check the console for errors.
      If you see this error, it means that the tested website caused it. You can fix it or disable tracking JavaScript errors in TestCafe. To do the latter, enable the "--skip-js-errors" option.
