I am completely new to vibe coding (0 coding knowledge). I generated a PDR with a non-Replit AI, ran it through Replit through the code mode. It ran for 44 min and the preview doesn’t show up. It came up with the following error code. I can view the thumbnail from my project space, but unable to actually view the full thing in the preview panel. Help!
