I am migrating an Azure Functions application from Runtime v2 to v4 and .NET 6. The functions app includes Durable Functions. Migrating the code was straight forward and I had no issues running locally. However, when I published to production, I started seeing this error. I thought it was related to me also trying to use Managed Identity and Key Vault but I have since taken those elements out and I am still getting the error below.
The error happens immediately during app startup so it seems to not be an issue with the actual functions but in the initial setup connecting to Azure Storage.
I have posted a question in the Azure Functions Host on GitHub but I haven't received much help.

How is your connection to AzureWebJobsStorage configured with? Using ConnectionString or with an Identity?
I have tried 3 options. All with the same result.
I have used the Identity configuration of "AzureWebJobsStorage__accountName" with the name of the Azure Storage account as the value.
I have tried standard configuration of "AzureWebJobsStorage" but using the Key Vault value like @Microsoft.KeyVault(VaultName=*********;SecretName=**********)
I have tried standard configuration of "AzureWebJobsStorage" using the storage connection string "DefaultEndpointsProtocol=https;AccountName=**********;AccountKey=********;EndpointSuffix=core.windows.net"
I actually don't think it is an issue with the configuration. I suspect it may be an issue related to Durable Functions or some corruption on the host.
Should we try create a new Azure function and deploy there and see whether the issue persists?
@Andrew Hawes Thanks for reaching out. The product team is looking into this and will share an update on your created GitHub issue here.
