Repro steps

Provide the steps required to reproduce the problem:

1. Create a Function 2.0
2. Create a GPv2 storage account
3. Setup a static website within the GPv2 storage
4. Attempt to use the Azure Blob Storage output method within the function to the new $web container

Alternatively set function to be triggered by $web, function will not run at all and no errors appear.

Expected behavior

Provide a description of the expected behavior.

Function should output a blob to the $web container with no issues.

Actual behavior

Function throws error message:

*** [Error] Executed 'Functions.****' (Failed, Id=***)
Validation failed for property 'BlobPath', value '$web/index.html'. The field BlobPath is invalid.

Known workarounds

Use the Node.js preview library and upload the blob within the function itself.

The same applies to C# (runtime 2.0.12246.0, NuGet package v3.0.2).

Just hit this myself C# .NET Core 2.2, NuGet package v3.0.6

Any movement on this? I just hit this issue with a JavaScript function. Runtime version: 2.0.12641.0

@3xj Doesn't seem to be anything, I had to rewrite the output functionality to get my function to work.

Adding my +1, seems this isn't moving very fast.

It's been reported here too: #3804.

It's working fine if you upgraded to lastes version of the nuget package for example "Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.4"
