Session Goal:

The session aimed to troubleshoot and resolve 502 Bad Gateway errors in a Google Cloud Platform (GCP) application deployment, focusing on dependency management, file system permissions, and session management.

Key Activities:

• Troubleshooting 502 Errors: Explored dependency management, Gunicorn configuration, and filesystem permissions to address 502 errors.
• Read-Only File System Management: Implemented solutions for handling GCP’s read-only file system using Flask, including session management and data storage.
• Function Adaptation: Modified the record_interaction function for GCP compatibility, utilizing the /tmp directory for temporary storage.
• Dependency Management: Updated requirements.txt with compatible module versions for the base2 environment.
• Login Redirection Analysis: Investigated and resolved login redirection issues in the application, focusing on OAuth and URL handling.

Achievements:

• Successfully identified and resolved the causes of 502 errors related to missing dependencies and file system issues.
• Updated module versions and improved file writing solutions for GCP.
• Enhanced session management and error handling in Flask applications.

Pending Tasks:

• Further testing of the updated requirements.txt for compatibility before full deployment.
• Continued monitoring of OAuth redirection handling to ensure stability in login processes.
