Fix CodeExecutionError

✅ Solution

The CodeExecutionError in dspy often arises from issues with how Python interpreters serialize and deserialize data, particularly with large integers exceeding JavaScript's safe integer limit (2**53) or non-JSON-safe values like NaN and Infinity. To fix this, ensure all data passed to or returned from the interpreter is strictly JSON-serializable, which may involve casting large integers to strings or representing NaN/Infinity with null or a specific sentinel value recognized by your application logic.
