Graceful shutdown missing for `unhandledRejection` and `uncaughtException`

[Sumith-Kumar-Saini]

In server.js, runtime errors trigger process.exit(1) immediately, bypassing gracefulShutdown(). This can leave DB/Redis connections open.

Code Reference:
server.js lines 8-17:

process.on('unhandledRejection', ...);
process.on('uncaughtException', ...);

Both call process.exit(1) directly without leaving any room for graceful shutdown.

Expected Behaviour:
Runtime errors should trigger gracefulShutdown() to cleanly close the HTTP server, MongoDB and Redis connections before exiting.

Suggested Fix:
Wrap both error handlers to await gracefulShutdown() before termination:

process.on('unhandledRejection', async (...) => {
  logger.error(...);
  await gracefulShutdown();
});
process.on('uncaughtException', async (...) => {
  logger.error(...);
  await gracefulShutdown();
});
