Azure function app (v4 / node.js) no functions found after zip deployment

Question

I have deployed a function app and there are no functions visible:

In Kodu what I can see seems correct (the files are under wwwroot):

In the app files tab. I can see two folder separators that I'm guessing this could be the problem:

I have WEBSITE_RUN_FROM_PACKAGE disabled and I'm deploying with:

az functionapp deployment source config-zip -g <resource-group> -n <app-name> --src ./deploy.zip

Answer 1

After trying millions of things, this is what did it for me:

My folder structure is the following:

dist <-- this folder is present if you use TypeScript
│   └── src
│       ├── dal
│       ├── functions
│       │    └── <MY FUNCTIONS ARE HERE>
│       └── shared
├── host.json
└── package.json

One of my changes was in the host.json:

  // ...
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.0.0, 5.0.0)" <-- upgraded the version
  }

Another thing I did was to upgrade everything (Azure CLI, function core tools, etc.).

And finally, I saw this in the docs:

During preview, the v4 model requires you to set the app setting AzureWebJobsFeatureFlags to EnableWorkerIndexing. For more information, see Enable v4 programming model.

To create it I needed to run:

az functionapp config appsettings set --name <FUNCTION_APP_NAME> \
--resource-group <RESOURCE_GROUP_NAME> \
--settings AzureWebJobsFeatureFlags=EnableWorkerIndexing

Then I restarted the function app and it finally worked.
