Description

Using some models may make mem0 internal responses generating JSONDecodeError:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The response from Mem0 LLM is below (using diff as code block format because the triple backticks "```" does not show at the code block below, so ignore these that at the first of a line).

  ```json
  {
      "memory": [
          {
              "id": "(UUID)",
              "text": "I'm visiting Paris",
              "event": "ADD"
          }
      ]
  }
  ```
