Isolated blob trigger function with Identity based connection throws exception

### Description

We have a .net8 isolated function for a blob trigger, with all roles added for the storage account to use identity based connection.
Same function is running in .net6 but with in-process worker runtime without any issues.
We updated the functions to .net 8 isolated, but the blob trigger function throws an exception when the trigger is called.
It is working fine if we use it without identity based connection, only with storage account connection string.

For test I have used a new function, an empty one, how it is generated with visual studio, I just added the connection name and the container name, and also the local.settings.json

### Steps to reproduce

Create new function project for a blob trigger
Use identity based connection to get blobs
Start function and add a blob to the container
local.settings.json ('BlobConnection' is my connection name prefix):
{ "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "UseDevelopmentStorage=true", "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated", "BlobConnection__serviceUri": "https://.blob.core.windows.net", "BlobConnection__clientId": "" } }
