Azure Static Web App returns 404

Question

I created Azure Static Web App back in 2020 when static apps were in preview. Since then my static site worked fine until today when I found out it returns 404. I can't even tell for how long site was broken (not really checking it too often). My site consist of single hand-made index.html, css and couple of other files.

I tried to redeploy, GitHub actions doesn't reveal anything suspicious:

(for version with staticwebapp.config.json I'm of course getting output regarding detection of new config and not using routes.json; at the beginning, I was using preview version of Azure/static-web-apps-deploy but now having v1)

My current routes.json looks like this:

{  
  "routes": [  
  {  
    "route": "/*",  
    "serve": "/index.html",  
    "statusCode": 200  
  }],  
  "defaultHeaders": {  
    "content-security-policy": "default-src https: 'unsafe-eval' 'unsafe-inline' cdn.jsdelivr.net *.mapy.cz",  
    "x-frame-options": "deny",  
    "feature-policy": "accelerometer 'none'; camera 'none'; geolocation 'none'; gyroscope 'none'; magnetometer 'none'; microphone 'none'; payment 'none'; usb 'none'",  
    "permissions-policy": "accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=()"  
  }  
}  

I just discovered routes.json is deprecated and staticwebapp.config.json should be used (https://learn.microsoft.com/en-us/azure/static-web-apps/configuration) - so I created:

{  
  "routes": [  
    {  
      "route": "/example",  
      "rewrite": "/example.html"  
    }  
  ],  
  "navigationFallback": {  
    "rewrite": "index.html",  
    "exclude": [".well-known/*", "css/*"]  
  },  
  "globalHeaders": {  
    "Content-Security-Policy": "default-src https: 'unsafe-eval' 'unsafe-inline' cdn.jsdelivr.net *.mapy.cz",  
    "Feature-Policy": "accelerometer 'none'; camera 'none'; geolocation 'none'; gyroscope 'none'; magnetometer 'none'; microphone 'none'; payment 'none'; usb 'none'",  
    "Permissions-Policy": "accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=()",  
    "X-Frame-Options": "deny"  
  }  
}  

... but even with this setup, it still doesn't work and I'm getting 404.

Structure of my repository is following:

/  
├─ .github/  
│  ├─ azure-static...yml  
├─ public/  
│  ├─ .well-known/  
│  │  ├─ security.txt  
│  ├─ css/  
│  │  ├─ style.css  
│  ├─ index.html  
│  ├─ robots.txt  
│  ├─ routes.json  
│  ├─ staticwebapp.config.json  
├─ .gitignore  

My GitHub actions job looks like this - notice app_location to be set to "public" - matching public directory name where my static content is:

jobs:  
  build_and_deploy_job:  
    if: github.event_name == 'push' || (github.event_name == 'pull_request' && github.event.action != 'closed')

    steps:

        with:  
          submodules: true

        uses: Azure/static-web-apps-deploy@v1

          ###### Repository/Build Configurations ######  
          app_location: "public"  
          ###### End of Repository/Build Configurations ######  

Could anyone help me figure out what am I doing wrong, what do I miss?

Answer 1

I wasn't able to solve it, technical support was clueless. The easiest option is to just ditch your old deployment and start with new one.

Answer 2

Has there been any progess on this issue ?

I find that no matter what I do with my config, I'm still getting 404 on the default page (index.html)

Dropping and recreating the site completely doesn't resolve it. How can we get some resolution on this as it's quite frustrating and seems to be impossible to figure out what's actually going on.

I'm using Vitepress, everything works as expected when run locally, but when deployed to Azure Static Websites, I get 404's on the main site URL, and then even directly navigating to the page (/index.html) it shows the 404 until i SHIFT+REfresh (which is a browser cache issue even though I've defined no caching.

Do I have to open a support ticket for this ? WOuld that even do any good based on the feedback above that support hasn't been able to fix it.

Answer 3

I didn't touch anything for several weeks and suddenly I start getting 404 as well...

Solve it by upgrading my subscription to "pay as you go".

There was message in subscription:
"Your free credit has expired. Upgrade to keep going with your account."
