**Cause:** The error message indicates that SQLite3 does not have a `JSON_VALID` function, which is required for the `execute()` method. **Solution:** The error suggests that you are using an older version of SQLite3 that does not include the `JSON_VALID` function. To resolve this, you can either: 1. **Upgrade SQLite3:** - Install the `sqlite3` package with the following command: `pip install sqlite3` or `pip3 install sqlite3`. - Update the `django-sqlite3` app to a version that supports `JSON_VALID` (e.g., 2.0.0). 2. **Use a compatible SQLite3 version:** - Ensure that your SQLite3 version is compatible with your Python version. The official documentation recommends using SQLite3 version 3.37 or later with Python 3.6 or later. **Additional Notes:** - The `json` module is not related to SQLite3 and is not mentioned in the context. - The `JSON_VALID` function is only available in SQLite3 versions 3.37 and later. - Upgrading SQLite3 may require administrator privileges or system package management tools.
