Monitoring and Debugging Errors in Absinthe GraphQL APIs with AppSignal

The article explains the challenges associated with tracking errors in GraphQL APIs, specifically when using Absinthe. It highlights that while GraphQL offers many advantages over REST APIs, it comes with its own set of error types, including schema validation errors, query syntax errors, resolver errors, and type mismatch errors. To demonstrate how to effectively track these errors, the author provides a tutorial on integrating AppSignal, a monitoring tool, into a Phoenix app that uses Absinthe. The process involves setting up the AppSignal package, configuring it correctly, and implementing custom middleware to ensure specific errors are reported accurately in the AppSignal dashboard. This article serves as both a practical guide for developers dealing with GraphQL errors and a comprehensive overview of how to achieve better error tracking in Elixir applications using AppSignal.
