Fixes #4315 Modify `prepare_global_scope` function in `src/backend/base/langflow/utils/validate.py` to evaluate classes, functions, and variables defined outside the Component's class. * **Function Changes:** - Add evaluation of external classes using `ast.ClassDef`. - Add evaluation of external functions using `ast.FunctionDef`. - Add evaluation of external variables using `ast.Assign`. * **Unit Tests:** - Add tests in `src/backend/tests/unit/test_validate_code.py` to verify the evaluation of external classes, functions, and variables. - Include tests for multiple external classes and external variables and functions. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/langflow-ai/langflow/issues/4315?shareId=XXXX-XXXX-XXXX-XXXX).
