Functions V4 - Require a minimum version for supported extensions

[goanwied]

Hello @paulbatum

I experience a similar issue as @heavenwing has. I upgraded an azure function to v4 and currently receive the following error in Azure Portal.

Microsoft.Azure.WebJobs.Script.ExternalStartupException : Error building configuration in an external startup class. ---> Microsoft.Azure.WebJobs.Script.HostInitializationException : One or more loaded extensions do not meet the minimum requirements. For more information see https://aka.ms/func-min-extension-versions. ExtensionStartupType AzureStorageWebJobsStartup from assembly 'Microsoft.Azure.WebJobs.Extensions.Storage, Version=3.0.11.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not meet the required minimum version of 4.0.4.0. Update your NuGet package reference for Microsoft.Azure.WebJobs.Extensions.Storage to 4.0.4 or later

I have applied some changes, such as applying the WEBSITE_RUN_FROM_PACKAGE = 1 in the config of the Azure function and updating to CICD pipeline to deploy as runFromPackage.

Also I added the package Microsoft.Azure.WebJobs.Extensions.Storage to the project, however still receiving the above error.

Interestingly I can see the my queue or time triggered function have been executed.

I have the same error after upgrading my packages and upgrading from runtime 3 to 4. I then removed the <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="5.2.1" /> from my project and still same error.
