One useful aspect of error management is the ProblemDetails class, which provides a standardized way to convey error information for different HTTP status codes like 400, 401, 403, and more. In this guide, we will explore how to create a custom ISchemaFilter for managing ProblemDetails effectively. Understanding ProblemDetails The ProblemDetails class is a part of the Microsoft.AspNetCore.Mvc namespace. It contains several properties that convey essential error information in a structured format. Some of the key properties include: type: A URI reference that identifies the problem type. title: A short, human-readable summary of the problem type. status: The HTTP status code generated by the origin server for this occurrence of the problem. traceId: An identifier for tracing requests, especially useful for troubleshooting. errors: A collection of errors, which is particularly useful for validation failures. By representing error responses using the ProblemDetails class, you can provide detailed and user-friendly error messages to clients consuming your API. Creating ISchemaFilter To create a custom schema filter for ProblemDetails, you can implement the ISchemaFilter interface. In this implementation, you can specify different examples of ProblemDetails for different HTTP status codes. Here is how to do it step-by-step: Step 1: Implement the ProblemDetailsSchemaFilter Create a new class ProblemDetailsSchemaFilter that implements the ISchemaFilter interface. Begin defining the different examples for various status codes: [[See Video to Reveal this Text or Code Snippet]] Step 2: Implement the Operation Filter To make it easier to manage and apply ProblemDetails across multiple responses, you can implement an IOperationFilter. This filter leverages the examples created in the schema filter for each status code.

This ensures that your defined filters are used when generating Swagger documentation. [[See Video to Reveal this Text or Code Snippet]] Conclusion By implementing a custom ISchemaFilter and IOperationFilter, you can provide accurate and detailed ProblemDetails examples in your Swagger documentation for various HTTP status codes. This approach not only enhances the quality of your API documentation but also improves the overall developer experience for those consuming your API. With the current emphasis on clear communication and error handling in API design, taking the time to implement such solutions is always worthwhile. Happy coding!
