Error handling is an essential aspect of building robust and reliable REST APIs. When working with REST APIs, you need to anticipate and handle various types of errors that can occur during the API interactions.

One technique for error handling is to use try-catch blocks to catch specific errors that may occur in your code. By catching specific errors, you can handle them accordingly and provide appropriate error messages to the client.

Another technique for error handling is to __ the errors to the calling function or to the client. This can be done by using return codes or exceptions to indicate the occurrence of an error. By propagating errors, you can inform the client about the specific error that occurred and let them handle it accordingly.
