Endpoint URL Launch issue

[lokeshkri]

Description

What is wrong or what would you like to see improved? After going through the deployment process, post all steps completing successfully the URL link appears when clicked getting an error message.

upstream connect error or disconnect/reset before headers. retried and the latest reset reason: remote connection failure, transport failure reason: delayed connect error: 111

From devtools: chrome-error://chromewebdata/:1

   Failed to load resource: the server responded with a status of 502 ()

Environment

Describe your OS and dev environment (Codespaces, Dev Container, etc): Codespacess setup

You're seeing a 502 with the App Service URL or with the Codespaces URL? I saw the 502 with Codespace URLs this morning, and ended up working around that by changing my local port. If you are seeing 502s with App Service, then you'll need to check the App Service logs. My guide from another repo can help with that: https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/appservice.md

Thanks for filing!

Error is with Web App Service end point URL. Thanks for the pointers. This is the error message I am noticing in the WebContainer App.

Hm, that static folder should have been built in the prepackage step, from this line: https://github.com/Azure-Samples/rag-postgres-openai-python/blob/main/azure.yaml#L15C27-L15C64

Can you try running that step manually to see if it's perhaps error'ing?

cd frontend;npm install;npm run build

[lokeshkri]

Running the steps manually /redeployment potentially must have helped, seems the app is back up and running now. Many thanks!

Okay, App Service deployment can be a bit finicky, I'll keep my eye out for the issue. Closing this for now, glad it's working.
