Can't access mounted file share on Azure function python v2

Claire 60 Reputation points

Hi, I try to mount an Azure file storage to use with an Azure function in python v2. I followed those instructions :

    "name": "datafiles",
    "slotSetting": false,
    "value": {
      "accessKey": "...",
      "accountName": "analyses",
      "mountPath": "/mnt/datafiles",
      "shareName": "datafiles",
      "state": "Ok",
      "type": "AzureFiles"

But the /mnt directory is still empty when I try to reach it from the function app. I went to Azure portal and don't have a "Path Mapping" tab in the Configuration part of the Azure function (only "Application settings" and "Function runtime settings". My function is quite simple :

import azure.functions as func
import logging
import os

app = func.FunctionApp() 

@app.route(route="test", auth_level=func.AuthLevel.ANONYMOUS)
def listfile(req: func.HttpRequest) -> func.HttpResponse:
    path = req.params.get('path')
    g = ""
        g = os.listdir(path)
    except Exception as e:
    return func.HttpResponse(

Any ideas ?
