Unable to Connect to Local Server - net::ERR_CONNECTION_REFUSED on Signup

[ajamous]

Hello,

I was trying to play around with this, have recently built it using the following commands as instructed by the documentation:

flutter build web --dart-define-from-file=dart_define.json
dart run tool/extenvsubst.dart dart_define.json build/web/index.html
flutter run -d chrome

After successfully building and running the application, I encountered an issue during the signup process. When clicking on the signup button, the application attempts to make a GET request to http://localhost:4000/api/v1/system-info, but it fails with the following error in the console:

GET http://localhost:4000/api/v1/system-info net::ERR_CONNECTION_REFUSED

This error indicates that the application is unable to establish a connection to the local serve running on port 4000r. Here are the details of the environment and steps I have taken:

• Flutter Version: :

Flutter 3.13.6 • channel stable • https://github.com/flutter/flutter.git
Framework • revision ead455963c (35 hours ago) • 2023-09-26 18:28:17 -0700
Engine • revision a794cf2681
Tools • Dart 3.1.3 • DevTools 2.25.0

• Operating System: macOS 14.0
• Browser: Google Chrome Version 117.0.5938.92 (Official Build) (arm64)
• Server Status: I have checked the server localhost:4000 is not running, I also was unable to find out where to run it from.

curl http://localhost:4000
curl: (7) Failed to connect to localhost port 4000 after 6 ms: Couldn't connect to server

Questions:

1. Server Connection: Is there anything specific commands that needs to be run separately to get the local server on port 4000 to run
2. Client-Side Configuration: Is there any additional client-side configuration required in the Flutter app to successfully make requests to the local server?
3. Debugging Suggestions: Are there any additional debugging steps or tools that you would recommend to diagnose and resolve this issue?

Thank you for your time and assistance!

@ajamous, thank you for bringing this to our attention. I believe you're the first person not from WebTrit dev team to run the app directly from the source – kudos! 🎉

The root cause of this error is the app's default configuration for a local WebTrit system dev deployment. However, we do have the Demo WebTrit system accessible at https://core.demo.webtrit.com. To run the app, simply set WEBTRIT_APP_CORE_URL to this value. Alternatively, you can manually enter this by opting for the custom WebTrit system login flow - just click on the chain icon at the top right corner of the login screen.

One heads-up: currently, the app is optimized for a mobile layout. A desktop-friendly design is certainly on our roadmap.

@ycherniavskyi Thank you for the extra information. I'll attempt it again and keep you updated on my progress.

Would you like me to create a pull request with the additional details you've given, to prevent future users from encountering the same issue?

@ycherniavskyi I changed the variable WEBRTIT_APP_CORE_URL to https://core.demo.webtrit.com/ as advised, now I get the following error when I click Signup:-
