I have an azure app function, very basic that runs well when deployed but locally, when I’m sending a post request it just get stuck and eventually the whole shuts down with the message shown below. When I comment out the line from azure.storage.blob import BlobServiceClient, the whole works and a response is returned.

My code:

import azure.functions as func
from azure.storage.blob import BlobServiceClient

def main(req: func.HttpRequest) -> func.HttpResponse:
    return func.HttpResponse(
        body="response",
        status_code=200
    )

the function.json file:

{
    "scriptFile": "__init__.py",
    "bindings": [
      {
        "authLevel": "function",
        "type": "httpTrigger",
        "direction": "in",
        "name": "req",
        "methods": [
          "post"
        ]
      },
      {
        "type": "http",
        "direction": "out",
        "name": "$return"
      }
  
    ]
  }

The command to trigger:

curl -X POST http://localhost:7071/api/TestFunc -H "Content-Type:application/json" -v -o -

The command window gets stuck in this operation. The azure environment is started in a venv using func host start.
The azure terminal shows: Executing 'Functions.TestFunc' (Reason='This function was programmatically called via the host APIs. and nothing else after that.

Is there any more info that I can provide to help find the solution? Does someone know what I can do to solve this issue? Having to deploy everytime to test is annoying.
