Python list comprehension throwing KeyError when returning key-value item on an if-else statement

The deviceResponse field throws a KeyError as responseText does not always exist in json_data entries. One way to resolve this is by adding this field in if missing in any entry, but is there a way to fix the deviceResponse field to return

• empty string if no responseText
• entire responseText if it’s a string
• just [“responseText”][“elements”] if that exists

returned_list = [
      {
        "deviceResponse": i["payload"]["responseText"] if  i["payload"]["responseText"] and isinstance(i["payload"]["responseText"], str) else i.get("payload", "").get("responseText", "").get("elements", ""),  
        "timestamps":[
            {
              "eventTime": i["header"]["eventTime"]["timestamp"]
            }
        ]
      } 
      for i in json_data if i["header"]["customer"]["id"] == customer_id
]
