New created app fails to run with an error APP_UNINSTALLED webhook delivery failed

Technical Q&A

Topic summary

A developer new to Shopify is encountering an error when attempting to run a newly created test app.

Setup Process:

  • App created using npm init @app@latest
  • Error occurs when running npm run dev -- --verbose --tunnel-url https://

Error Details:

  • The main error message is: APP_UNINSTALLED webhook delivery failed
  • Additional error: App hasn't started in time, giving up
  • Connection error also appears: Error: connect ECONNREFUSED 127.0.0.1:19597

Technical Context:
The verbose logs show Express router initialization and Remix server attempting to start on localhost:34841, but the app fails to start within the expected timeframe. This prevents the webhook system from successfully delivering the APP_UNINSTALLED webhook.

Current Status:
The issue remains unresolved with no responses or solutions provided yet. The problem appears to be related to app startup timing and webhook configuration in the development environment.
