langchain - 💡(How to fix) Fix [BUG] Memory store health check endpoint missing [1 participants]

1. Receive 404 Not Found error

Fix Plan

The fix involves ensuring the health check endpoint is properly configured and exposed.

Steps to Fix

• Verify the endpoint is defined in the routing configuration:

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/memory-store/health', methods=['GET'])
def health_check():
    return jsonify({'status': 'ok'})

• Check if the endpoint is correctly registered in the application:

if __name__ == '__main__':
    app.run(debug=True)

• Ensure no conflicting routes or middleware are blocking the endpoint.
• If using a reverse proxy or load balancer, verify the endpoint is properly proxied.

Verification

• Restart the application and execute the smoke test again.
• Attempt to access the /memory-store/health endpoint directly using a tool like curl:

curl http://localhost:5000/memory-store/health

• Verify the response is {"status": "ok"}.

Extra Tips

• Regularly review routing configurations to prevent similar issues.
• Consider implementing automated tests for critical endpoints like health checks.
