What steps would you take if an error occurs when transmitting data to a NoSQL database?

When a data transfer error occurs in a NoSQL database in Node.js, the following steps should be taken:

1. Error logging — save error details for later analysis.
2. Check database connection — ensure the database is accessible and the connection is active.
3. Data validation — verify that the data is correct and meets schema requirements (if any).
4. Exception handling — use try/catch or promise handlers to properly catch errors.
5. Retry writing — implement retry logic with exponential backoff if the error is temporary.
6. Notification — notify the team or monitoring system in case of critical errors.

Example of error handling when writing to MongoDB using async/await:

try {
  await collection.insertOne(data);
} catch (error) {
  console.error('Error writing to database:', error);
  // You can implement a retry or other logic
}
