I was trying to submit the practical exam zip file online but the website throws a pop up message as below. Can someone please assist ASAP. I still have 1 hour left to submit my code,


Welcome back to our uipath community.

This certification site was retired on 30th April 2020 as Uipath introduced two new certifications and because of that you are getting this error.

But it is still open to the people who started their course earlier I beleived.

@swathyn, please send an email to certification@uipath.com.
Thank you.
