Issue with Azure Blob Storage Connection After Deploying Azure Functions

Issue

I deployed an Azure Functions app using the Blob trigger template directly from Visual Studio Code. Despite selecting an existing Azure remote storage account, when I check the function’s “Integration” tab in the Azure portal and select “Trigger,” the “Storage account connection” field is grayed out and displays “Click select to choose a connection” What could be causing this issue, and how can I resolve it?

code: function_app.py

import azure.functions as func
import logging

app = func.FunctionApp()

@app.blob_trigger(arg_name="myblob", path="mycontainer",
                               connection="storagesample_STORAGE") 
def blob_trigger(myblob: func.InputStream):
    logging.info(f"Python blob trigger function processed blob"
                f"Name: {myblob.name}"
                f"Blob Size: {myblob.length} bytes")
