Prepcourse Backstage - yarn dev not opening server

Lab Support
#1

Litrerally just trying to get the app to run. It’s beyond frustrating. To clarify, i have reset this lab, i have even ensured i followed the ‘solution’ to ensure it’s correct as i’m not taking the task details - considering 1 of them is incorrect (reported) every stage has been ticked until you get to stage 4 - cant seem to run the server. I’ve wasted a good 1 hour+ on this.

yarn dev

the automatic window that pops up whilst running the server errors with: connect ECONNREFUSED 0.0.0.0:3000

pressing the ‘backstage’ button on the tutorial results in: 502 Bad Gateway

Asked AI - that is telling me to remove ‘“app”: “link:…/app”,’ from package.json and all sorts - it hasn’t got a clue, every bit of advice (such as adding in a proxy) i’ve tried and it’s still failed.

The lab is a bit confusing because when you first start it, it actually won’t work – that’s part of the lab. If you continue to the next step, it walks you through how to fix it. So keep going. I just went through the lab, and it works to the end of the lab once you do that. The solution tabs, though a bit involved, will show you what to do.
