/**
* A pretty error handler for rendering error pages. When working in development mode
* exception details will be returned in the server responses, otherwise or when
* manually specified no exception details are returned in the HTTP response.
*
* The reason the display of the exception details is by default dependent of the mode
* is to follow the security best practices:
* https://www.owasp.org/index.php/Improper_Error_Handling
*
*
* NOTE: This class has been automatically generated from the {@link io.vertx.ext.web.handler.ErrorHandler original} non RX-ified interface using Vert.x codegen.
