Test Backend Integration with Vertex AI Using a Local Test Prompt

Description:
Conduct a local test of the backend API integration with Vertex AI by sending a sample prompt to verify that the service generates accurate and meaningful responses. This ensures that the backend setup is functioning as expected before proceeding with frontend integration.

Acceptance Criteria:
The backend API successfully sends the test prompt to Vertex AI and receives a response.
The generated questions are accurate and align with the test prompt.
Any issues encountered during the test are documented and resolved.

Start by locating the backend API integration and the Vertex AI request path, then run the service locally with a sample prompt. Done means the API receives a response, the generated questions match the prompt accurately, and any issues found during the test are documented and resolved.
