Question

Hi Team,

I have upgrade Azure function from .Net6 to .Net 8 isolated and could not able to read QueueName and connection from app settings.

below is my code

[Function("Function1")]

public async Task Run([QueueTrigger("%FuncAppSettings:QueueName%", Connection = "FuncAppSettings:StorageConnection")] string queueItem)

{

  try

  {

     }
```}      

App settings:

 "FuncAppSettings": {

   "QueueName": "myqueue",

   "StorageConnection": "***"

 },

It was working before(.Net6) after upgrading to .net 8(Isolated) its not working.
