Add ServerWebExchange as hint in SentryWebExceptionHandler

[usrivastava92]

Problem Statement

Problem:
In SpringBoot Webflux, exceptions are intercepted by the SentryWebExceptionHandler. Here, a SentryEvent is generated prior to invoking hub.captureEvent(event, hint);. Both ServerHttpRequest and ServerHttpResponse are embedded in the Hint object. Given that the same Hint and Sentry Event objects are forwarded to SentryOptions.BeforeSendCallback, information derived solely from the request or response can be utilized to establish logic within BeforeSendCallback.

This creates a limitation where if a user intends to utilize exchange attributes within BeforeSendCallback to formulate logic, they are restricted from doing so.

An easy fix for this problem involves setting ServerWebExchange as a property in internalStorage map of the Hint object

Hello @usrivastava92 thanks for the feedback. I presume simply adding ServerWebExchange to Hint, e.g. as WEBFLUX_EXCEPTION_HANDLER_EXCHANGE would solve the problem, correct?

@adinauer that is correct, here is the PR to fix this 🙂
