2. **Issue**: Email address that cannot be reached in the 'Authors' section of task.json
    - **File**: task.json
    - **Evidence**:
        ```json

            "created_date": "2022-09-15"
        }
        ```
    - **Description**: The email address "ethan.hart@invalidemail.com" specified as the author's contact email in the task.json file is flagged as an invalid email address. This renders it impossible for users or collaborators to reach out to Ethan Hart regarding any queries or discussions related to the task.

3. **Issue**: Email address that cannot be reached in the 'Authors' section of dummy_model.transcript.md
