Hi Mars,The below steps is based on my specific example and I can’t guarantee it will work in your specific case. But several comments from other users prove that the solution works, as they have managed to successfully pass by this error following the steps below.1- Delete the existing Chatter group2- Delete it from the bin as well3- Wait for 5-10 minutes4- Try to Check Challenge again5- The error should disappear and be replaced by a challenge related message like ‘Couldn’t find ...Chatter group ’ (“3. Create Again”)6- Now try to create the deleted Challenge file. Make sure you don’t make any mistake in the name, as for some people error appears when they rename.I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.Thanks and Regards,Deepali Kulshrestha
