How to Use errors.WithMessage() in Golang

In Go programming, the WithMessage() method, part of the error package, enhances error handling by annotating errors with additional messages, providing crucial context for debugging without altering the original error value. This method is particularly useful in situations where the basic error handling technique, such as checking if err != nil, doesn't provide sufficient context. The text provides examples demonstrating how WithMessage() can be used to add context to errors, showing how it retains the original error information while appending a descriptive message. It also introduces Rollbar as a tool that automates error monitoring and triaging, facilitating real-time error tracking and management to improve the deployment process in production environments.
