Key Activities

• Configured the Flask application for deployment on Google App Engine, focusing on the create_app() function and Gunicorn settings.
• Addressed the ‘Failed to find application object’ error by verifying import paths, the application factory function, and environment configurations.
• Debugged deployment issues by checking the app.yaml configuration and ensuring the correct placement of main.py.
• Enhanced the Flask application’s main.py with logging capabilities to facilitate debugging.
• Utilized Git to clone older versions of the repository for local testing and incremental updates.

Achievements

• Successfully configured the Gunicorn entry point in app.yaml and resolved the create_app() function error.
• Improved logging setup in the Flask application to capture deployment logs effectively.
• Identified and resolved key deployment issues, ensuring the Flask application runs smoothly on Google App Engine.
