Hallo everybody,
I want to create a blob trigger azure function and I have an error which I hope you can help me. After creating a blob trigger function I got this host.json file:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[3.*, 4.0.0)"
  },
  "concurrency": {
    "dynamicConcurrencyEnabled": true,
    "snapshotPersistenceEnabled": true
  },
  "extensions": {
    "durableTask": {
      "storageProvider": {
        "type": "AzureStorage"
      }
    }
  }
}

Now, I got the error "Property type is not allowed: Unfortunatelly I am not able to find something useful in the internet so I am hoping that you can help me.

With kind regards,
Gerald

@Gerald Rupp Looks like the type property is not defined in the schema for host.json, but this error itself should not cause any issues when running Azure Functions.

We will work on getting this updated to fix the experience from the editor perspective.

So I understand you correctly, that for now I can ignore that error and do not have to change my host.json file in any way?

@Gerald Rupp Yes. That is correct. In fact, you could remove the extensions part of your host.json since that is the default setting already.

@Pramod Valavala , I'm still seeing the same issue. I guess this has not been resolved yet.
