In some cases, it may be more efficient to define this error handler as part of your code. The outcome being that when an unexpected error occurs then a generic response is returned by the application but the error details are logged server side for investigation, and not returned to the user.\n\nThe following schema shows the target approach\n\nAs most recent application topologies are API based, we assume in this article that the backend exposes only a REST API and does not contain any user interface content. The application should try and exhaustively cover all possible failure modes and use 5xx errors only to indicate responses to requests that it cannot fulfill, but not provide any content as part of the response that would reveal implementation details. For that, RFC 7807 - Problem Details for HTTP APIs defines a document format. For the error logging operation itself, the logging cheat sheet should be used. This article focuses on the error handling part.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
